As per Ehrenreich, the various syndicated programs that are available in the program calendars of different telecom companies satisfy an ethical capacity; in any case, these shows are additionally innately exploitative of the helpless masses (21). Ehrenreich contends that, by empowering couples, families, and companions to uncover their insider facts in broad daylight, and accordingly offering moral direction and restorative activity to the blameworthy gatherings in the different scenes, the syndicated programs administer a mutual good direction that plays a basic capacity in giving the liable visitors and the watchers a wellspring of moralistic reference.

Besides, when well known and decent female artists resort to promoting their self-perceptions more than the substance in the verses of their melodies through music recordings, the delineation of ladies as unimportant sexual performers is additionally improved. Taking everything into account, like the way that Barbara Ehrenreich’s contention that, daytime syndicated programs are misusing the poor in the p ublic arena, music recordings are abusing ladies and depict them in a negative light.

Take a stab at Global Heating: Causes. Effectss and Remedies Global warming is the best test standing up to earth. It is. actually. the expansion in the temperature of the earth’s neon-surface air. It is one of the most present and generally talked about elements. It has broad effect on biodiversity and climatic states of the planet. A few ebb and flow inclinations unmistakably show that planetary warming is straight affecting on lifting ocean degrees. the defrost of ice tops and significant overall clime modifications. In short. planetary warming speaks to a cardinal threat to every single living thing on Earth. Worldwide mean temperature rose altogether during the previous century. The prevailing logical position is that the vast majority of the temperature increments since mid-twentieth century has been brought about by increases in barometrical nursery gas focuses created by human movement. Most researchers concur that planet’s temperature has risen 0. degree Celsius since 1900 and will proceed to increment at an expanding rate. As an outcome. the universe is securing radiator. The twelvemonth 1990 was the most sizzling twelvemonth in the only remaining century. Together with 1991. the mature ages of 1983. 1987. 1988 and 1989 have been estimated to be the hottest six mature ages in the last hundred mature ages. The twelvemonth 1991 was the second hottest twelvemonth of the previous century. The impacts of the ascent in temperature is being felt everywhere throughout the Earth the discoveries of logical research done in this field uncover that the temperature of the Earth is probably going to lift from 1. 4 °C to 5.  °C inside a time of 100 mature ages.

On the off chance that the precariousness keeps on lifting. one twenty-four hours this will introduce a request grade on the being of this planet. Carbon dioxide ( C02 ) which is an of import part of condition is doing a warming outcome on the earth’s surface. It expands the vaporization of H2O into the climate. Since H2O fume itself is a nursery gas. this causes still all the more warming. The warming makes more H2O fume be vanished. The C02 degree is relied upon to lift in future because of continuous burning of petroleum derivatives and landuse change. The pace of rise will rely for the most part upon uncertain monetary. sociological. innovative and characteristic turns of events. Different gases, for example, methane. Chlorofluorocarbons. azotic oxide. tropospheric ozone are other than liable for planetary warming. Increments in every one of these gases are because of unstable populace developing. expanded mechanical augmentation. innovative advancement. deforestation and turning urbanization. and so on. Trees play a significant capacity in the planetary C beat. They are the biggest land-based component for taking C dioxide from the air. You read A dangerous atmospheric devation and Human Population Essay in class Paper models Deforestation is look intoing these positive methods. It is the second standard reason for environmental C dioxide. Deforestation is answerable for 25 percent of all C spreads come ining the mood. by the ignition and film altering of 34 million homes of trees every twelvemonth. Ordinarily more than 5500 domains of downpour woods are decimated. As an impact of solid loss of woods. planetary CO. degrees ascend around 0. 4 percent every twelvemonth. the degrees non experienced on this planet for 1000000s of mature ages. As we probably am aware the forested areas are the incredible safeguards of CO. There is a nearby connection between planetary warming and populace developing. Today the large populace on Earth is using the engineerings which are damaging for the Earth. Roughly. 80 percent of environmental C02 increments are expected to man’s utilization of petroleum products either in the signifier of coal. gas or oil. A major piece of C radiation is credited to the burning of gasolene in inward ignition motor of vehicles. Vehicles with hapless gas milage contribute the most to planetary warming. Other than. the sulfur bunch gas is the most hurtful for this. Its part is 30 percent in planetary warming. This gas is other than radiated from the ignition of non-renewable energy sources. Increment in planetary temperatures will do ascend in ocean degree. It will take to runing of ice sheets. changes in precipitation structures. expanded quality and frequence of most extreme conditions. According to the most recent examination report the pace of defrost of ice sheets has seen fresh expansion as of late. Indeed, even those icy masses are influenced from planetary warming which have been viewed as enduring. The shrinkage of icy masses is making a trip to introduce a significant activity of soaking up H2O. The ocean degrees as a result of defrost of ice sheets have ascended from 0. 35 millimeter to 0. 4 millimeter. Researchers have cautioned in their examinations that a large portion of the icy masses will disappear inside a time of 15 to 25 mature ages. It will make employments of guzzling H2O and supplement grains in a large portion of the North American states. India is non unaffected from it. The Himalayan icy masses have contracted around 30 percent after 1970. The ascent in ocean degrees is a significant reason for concern. A major figure of metropoliss situated in waterfront nations will submerse in the ocean. Other than. numerous island states will at last â€Å"lose their being and will be washed off from the outside of the Earth. The damage of lifting ocean degrees is various. Structures and streets close to the H2O could be overwhelmed and they could suffer hurt from typhoons and hurricanes. Specialists accept that planetary warming could expand the quality of storms by more than 50 percent. In add-on. as the ocean rises. sea shore disintegrating takes topographic point. unconventionally on steep Bankss. Wetlands are lost as the degree rises. Ascend in climatic temperature will take to the ejection of airborne and water-borne infections. It would other than loan to the ascent in perish brought about by heat. The activity of drouth would be visit. Subsequently. unhealthiness and famishment will introduce genuine test before mankind. Worldwide warming is an extraordinary danger to the vegetations and zoologies of the Earth. A major figure of types of them may go nonextant. The range of desert would increment. Low precipitation and lifting temperature could add to the quality and frequence of residue secured storm. This in curve will unfathomably affect the nature of agrarian land

Things That Can Help End World Hunger - Free Essay Example

Genetically modified foods have become present everywhere over the past few years. It is a breakthrough that allows humans to change and add manipulated genes to crops or alter or replace a gene to get a wanted trait, but it has turned into a heavily debated issue, especially for developing countries. Some people believe that these foods not only provide significant amounts of benefits to feed those in poverty in those countries, but they can also be a source of proper nutrition. In third world countries, malnutrition is a major cause of death, among the poor. For example of a solution, scientists have created a strain of yellow rice containing high amounts of vitamin A and many other nutrients. Also, genetically modified crops are seeped in herbicides and pesticides, and other treatments to help growth and survival of the crop, but then again so are regular crops. So if that is the call of complaints, maybe people should find out how the crops they consider natural are planted. Though there are many, including the large manufactures who claim GMOs are going to save the poor from starving such as in Africa. Africa has a different story to tell. Similarly, delegates from 18 African countries at a meeting of the UN Food and Agriculture Organization responded these claims with a clear statement: We strongly object that the image of the poor and hungry from our countries is being used by giant multinational corporations to push a technology that is neither safe, environmentally friendly, nor economically beneficial to us. We do not believe that such companies or gene technologies will help our farmers to produce the food that is needed On the contrary it will undermine our capacity to feed ourselves. (Earth Island Journal) According to Harvard University, the process is more straightforward than you will see on the internet and this process actually is producing results. In the past 10 years production of the staples such as beans and corn have increased nearly 30 percent. (Feeding the World One Genetically Modified Tomato at a Time: A Scientific Perspective) Staples are becoming hybrids of themselves, containing genes from Bacillus thuringiensis that work to control a number of serious problems such as insect pesticide and are now being utilized commercially in the United States. Using these will slowly get rid of the need to use those harmful insecticides. Improvements and great progress also has been made in the development of bettering staple foods such as corn and beans. The development of these plants could lead to a reduction in overall herbicide use. This should have both economic and environmental advantages, in theory. (Ending World Hunger. The Promise of Biotechnology and the Threa t of Antiscience Zealotry) The first thing to do if we truly want to end world hunger is accept this claim introduced by large corporations. This claim has no scientific backing whatsoever. The second barrier is the lack of research funds for agriculture and biodiversity (the variety of crops) and it is important to find solutions compatible with funding for research in genetic alteration of crops. Favoring biodiversity does not deny access to any future utilization of technology in the biological field but favoring biotechnology threatens future advances in biodiversity. (Feeding the world: genetically modified crops versus agricultural biodiversity) In other words, if we keep favoring the GMOs, we are stumping evolution and the natural order of things, therefore plant life will become severely limited. We will technically put the natural selection process in our hands. Whether or not this will be a good thing is yet to be seen. According to the Huffington Post, millions of children die due to inefficiencies in certain vitamins. (Can GMOs Help End World Hunger?) If we can stop these children from dying, I think it is worth the risks. Nothing values over human life. Sorry, plants.

A Disease Of Henrietta Lacks - Free Essay Example

Invading Doctors and Desperate Scientist Are doctors invading our body? When you go to the doctor you dont know what theyre doing all they tell you is youll get examined but they dont tell you exactly how. This happened to a young lady named Henrietta Lacks. They took a sample from her body and from there it was chaos. There were miracles but there was also devastation. It is essential to know what is going on in your body and also what doctors are doing to it. THE IMMORTAL LIFE OF HENRIETTA LACKS SUMMARY In the book The Immortal Life of Henrietta Lacks, a journalist and family go through a journey where they find out the importance of consent and their knowledge of medical complications. Part I: Life. Henrietta had a feeling there was something down in her cervix area. She would bleed on days that she wasnt on her menstrual cycle, she worried that this was something serious. She married her cousin day and had many kids. She later went to the doctor and was misdiagnosed with a tumor which ended up to be cancer. She did not tell any of her family about this she went back and forth to the hospital for treatment. The doctors took samples of Henriettas cancer cells without her consent and tested it against many diseases. Henrietta cells were the first ever human cells to ever survive under lab conditions perfectly healthy and reproduce. Henrietta was very fun, generous, and hard-working. She cared so much about her physical appearance especially her nails. Her cousin Sadie said that Henrietta would always keep her nails and toenails covered with fresh red nail polish. Henrietta was later hospitalized and the doctors did not allow her kids to visit her because it made her worry too much. Rebecca Skloot had contacted Deborah, Henriettas youngest daughter, about writing a book on her mother. Deborah was told to not tell Skloot any information so she had to go straight to the husband day but he did not want to give any information either. Later on, Rebecca got in contact with a woman named Courtney hello Courtney could not give much information she did show her an extraordinary documentary. Part II: Death. While collecting samples of Henriettas organs Mary, Geys assistant, sees the chipped nail polish on Henriettas toes and at that time she realizes that these cells come from an actual human being. Mary feels regret and remorse for this being because she can imagine her having fun and spending her time painting her toenails. A vaccine for polio was made with the help of Hela cells by Dr. Jonas Salk. Hela cells were then the first cells to be shipped by mail. Hela cells influence many things such as polio vaccine, cell cloning, a discovery that cells have 46 chromosomes, diagnostic of genetic disease, isolating stem cells, in vitro fertilization.   Henrietta family still does not know that her cells are still alive but there are still traces showing and hiding that Henrietta was a donor of Hela cells which makes Gey appear more as a villain. Deborah experiences awful abuse from Ethel and her husband Galen. Her children had moved to Lawrence and Bobettes but Galen still abuses Deborah. Bobette has convinced Deborah to stay in school and to fight off her cousins, Galen and Ethel. Chief of Urology at Sloan-Kettering Institute for cancer research injects people with Hela cells without their consent. Skloot writes that informed consent was not even a term until 1957 when a patient was paralyzed during what he thought was a routine surgery and successfully sued the surgeon. Stanley Gartler claims that Hela cells were contaminated, he finds a rare genetic marker called glucose-6-phosphate dehydrogenase-A (G6PD-A)which was exclusively in Black Americans. Skloot has gone to Lawrences house and is asked what the Hela cells have done that is so important. skloot finally meets Sonny, Lawrence, day, and Babette in one visit. she talks about the history of John Hopkins and discusses two cases of racism. One is about a lead poisoning in the late 90s. George gay learned that he had pancreatic cancer he wanted to become a founder of an immortal cell line and help researchers but he was not able to with cancer he obtained. he still wanted to help science so he under many chemo treatments which nearly killed him. after his death, Howard Jones took another look at Henriettas biopsy and finally realize that her tumor was misdiagnosed. Part III: Immortality.   Tibet finds out from her friend the Henrietta cells are still alive. She runs home and tells Lawrence who calls John Hopkins to ask about his mother cells. After 22 years her family finally learns that the cells are not only alive but are also bought and sold for research. The Hopkins geneticist volunteered his barely English speaking fellow researcher, Susan Hsu, to get blood from the Lacks family. Hsu and day to have a lot of miscommunication about consent because of clashing versions of English. Deborah generally thought that they were taking her blood for a cancer test and even got her blood taken out a second time. Mckusick frightened Deborah with a summary of experiments that were done with Hela cells because he assumed that Deborah already knew about everything that was going on with the Hela cells. he had given her a text booked thinking that it would help answer Debras questions but the only thing she understood was that there was a famous picture of her mother in the textbook. McKusick has said that he doesnt remember meeting Deborah or where he got in the picture of Henrietta from. The Lack of boys was angry that people were making money off of Hela cells. They initially thought that Gey and Hopkins stole Henrietta cells so they can make lots of money but it wasnt right. the boys started a movement to get hairdo from Hopkins but Deborah just wanted to understand. Deborah has suffered so much on her mother she lost and has spell betrayal about Hopkins actions. zakariyya is out of jail and sleeping on a bench across from his fathers home. he blames day for Henriettas death, for leaving the kids with Ethel who is abusive. A book called A Conspiracy of Cells: One Womans Immortal Legacy and the Medical Scandal It Caused, is published in 1985 by Michael Goulds. Deborah is found reading this book and falls apart at the description of her mothers painful death. BREAST CANCER RESEARCH The cell cycle begins with the interphase, which is the longest part of the cell cycle. It comprises three parts G1 phase, S phase, and G2 phase. The cells begin in the G1 phase where the growth, creation of new proteins, and organelles happen. They then move onto the S phase where DNA is replicated. Last, cells move to the end of Interphase, where they head to the G2 phase where organelles and molecules are made for cell division. The cells then move to M phase(Mitosis) where chromosomes are divided evenly and relax. After the M phase, the nuclei (relaxed chromosome) and cytoplasm divide to create two daughter cells in the Cytokinesis Phase. The cell cycle is crucial because it helps for the growing and development of organisms. Although the cell cycle is essential for us, it can put our health at risk if the process happens too quickly.   Cancer is caused when the cells reproduce uncontrollably and do not respond to the signals. Abnormal cells can start growing in the milk ducts and break out into the nearest breast tissue, which is what happens during breast cancer. Once these cancer cells begin, they can move from your breast into other parts of your body like the bloodstream and immune system. Some symptoms of breast cancer can be a lump in the breast, bloody discharge from the nipple, and changes of shape to the nipple or breast. Once breast cancer spreads, it can irritate the skin, cause swelling and pain, weaken the body, and cause unintentional weight loss. Things we are exposed to in our everyday life or our surrounding environment can affect our risk of breast cancer. Factors such as Ionising radiation, Medical X-rays, Radiotherapy treatments, Shift work (working at night), stress can put yourself at risk to get Breast Cancer. You can also be the one to be putting yourself at a risk. For example, eating a poor diet, inactivity, obesity, heavy alcohol use, smoking, exposure to chemicals/toxins do not help you but causes you to put yourself in a higher risk to Breast Cancer. If you are a person who is healthy, watches themselves, protects themselves from radiation, you have a less chance of getting diagnosed, but if it runs in the family, there is still a chance you are at risk. The mutated genes copy itself and are passed on genetically to future generations. There are no ways to prevent breast cancer, but there are ways to lower your risk such as watching your health and being physically active. Other factors are limit/avoid alcoho l, breastfeed, dont smoke, and avoid exposure to radiation or pollution.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There are many ways breast cancer is treated. The treatment depends on what stage of breast cancer the patient is in. Surgery, therapy, Medication, and even specialist are things people have to go through to cure their cancer. If you are in the early stages of breast cancer, it can usually be treated with medications, radiation, or therapy. But the later stages are treated with chemo, surgery, or even a specialist. The way doctors diagnose the cancer is by performing many exams. The exams comprise breast exams, a mammogram, a breast ultrasound, biopsy, or even an MRI scan. Those are the only way doctors can diagnose you and know what treatments are needed. About 1 in 8 U.S. women (about 12.4%) will develop invasive breast cancer over the course of her lifetime. Breastcancer.org. In 2018 an estimation of 266,120 cases of invasive breast cancer are diagnosed in women and about 2,550 cases of invasive breast cancer are diagnosed in men in the U.S. It is more common for women to be diagnosed with breast cancer. But men in their 60s or 70s are usually at a risk. As long as your body is healthy and there is no history of breast cancer in your family you are safe from being diagnosed. Although you can treat part of it, you still must be careful of what you do. Works Cited Skloot, Rebecca. The Immortal Life of Henrietta Lacks.

My Philosophy on Physical Education Essay - 616 Words

My Philosophy on Physical Education Physical education should be a fun class, but fun does not have to mean chaos. I believe in a structure that will allow the students to have fun in a safe way. My lesson plans will be structured so that students are constantly engaged in physical activity. I feel that if I can keep students moving and learning, then the chances of misbehavior will decrease. In elementary school I feel that Instant Activities should be used to get students moving when they get into my class. High school is a little different. I feel that students at the secondary school level should be introduced physical fitness activities that will help keep them in shape later on in life. Physical†¦show more content†¦My class will be competitive to a point. I want students to compete hard in team games, but not to the point where too much pressure is put on them. Motivation is the key to accomplishing any task. I plan to use both intrinsic and extrinsic motivation. The grade level of the class will determine what kinds of motivation strategies I will use. I do not believe in written work outside of class in my physical education class. Students are always bombarded with papers, problems, and reading. The occasional exit slip or written exam will be incorporated within my class, though. I want students to gain knowledge of sports, fitness, and their body. I believe that I am one of the few chances a student has to become interested in life-long activities. I want students to want to be physically active. I will show them the benefits of living an active lifestyle and try to incorporate ways that will always keep them interested in physical fitness. Community plays an important role in the development of the students. The community wants to know what there money is going to. There are also people who believe that physical education is a waste of their money and that high school students are too old for â€Å"recess†.

Essay on Human Civilizations Diversity in the World

Diversity within this world is what makes every one of us unique in our own way. The different cultures of the world are the principle of various human civilizations, which we have come to recognize and accept on a global level. As one of the largest countries in the world and one of the four ancient civilizations, China bears many cultural traditions and scientific developments that are extremely imperative and influential. Many aspects of the Chinese’s rich and profound culture could be traced back many centuries ago through its written history (China Highlights, 1998). Geographically, a green gemstone called jade is found in Burma, Central America, Brazil, Canada and India. Although prized by many other civilizations, no other†¦show more content†¦A legend claims that when the Mongols invaded China, the dragons mourned for the Chinese people. When the tears reached the Earth, they changed to jade (Todd, 2010). Another myth that has been recounted for many centuries is about a man named He Shi Zhi Bi, or Bian, who found a piece of uncut jade in the mountains of China. He immediately presented the stone to King Li who asked a craftsman to examine the gemstone. The craftsman declared that the piece of stone that Bian had found in the mountains was only an ordinary stone, therefore the king decided to amputate one of Bian’s leg for dishonesty and being disrespectful. It was not until the ascendant of the throne after Li, asked his craftsman to carve the stone and discovered the beauty and delicacy of the jade gemstone (Sator, 2008). Fro m then on, jade is known as â€Å"bi† in Chinese and is known as a symbol of beauty to the Chinese people (Shan, 2014). Jade played an important aspect in Chinese life when it came to producing fine objects such as tools and other necessities that are vital. During the Shang Dynasty around the 1600s, jade was used for personal embellishment and ornamentation by kings, as well as for utilitarian and ceremonial objects. Jade weapons such as knives and dagger-axes were created from the exquisite gemstone for every day, personal use or defense.

Slavery, Black Wall Street - 2450 Words

Jacqueline Turner GWST Dr. Rago 4/26/15 In my paper, I will be discussing capitalism, slavery, â€Å"Black Wall Street† and â€Å"White Wall Street. Racism and capitalism are intertwined. In order to ever racially balance capitalism, we will need to eradicate racism. This affects all of us, no matter our race. Capitalism is often seen as a dirty word. Who holds the power when it comes to capitalism? White males have historically been the power holders, and they still hold it today. They are seen as the educated and innovative creators of businesses, organizations, and corporations, past and present. Are they really that creative, educated, and innovative, or are they the only ones that have really been afforded the opportunities to be so? Capitalism flourished in areas where there was already a split in labor due to gender. It flourished in Britian, and then in Europe and the United States of America. If we look back on the 19th century, white men were out working, while the white women were caring for the c hildren and the home. Thank goodness this has changed some. Oh, the women are out working, they just aren’t getting equal wages as the men. Slavery and exploitation of minorities fortified the white man’s status and position as far as power and economics. White men owned all the capitalist organizations, factories, railroads, and businesses. White men pretty much owned everything and ran everything.

First, the opportunities of an industry are anything that is a possibility to improve and move that industry in to the future, all while giving competitive businesses an edge over the other to sway consumers one way or another. The opportunities of the fitness center industry mingle with the threats of the external environment they also face; however, with the right strategies and goals in place, both the opportunities and threats can hold an advantage and work in the industry’s favor. An opportunity that lies in front of the fitness center industry is that the current business of fitness is trending world-wide, it is a â€Å"get fit† society right now; with that personal trainers, group fitness courses, and children’s fitness courses are all opportunities to the industry.

Observations of Chemical Changes free essay sample

All substances (matter with a definite composition) have characteristics that be used to identify them. These characteristics are referred to as properties. The properties of substances can either chemical or physical. Physical properties are those that do not change the chemical nature of a substance. Dying an Easter egg blue will alter the appearance of the egg not it’s make up. If the nature of a substance were to be altered then the chemical properties have been affected. A good example of a chemical change can be seen repeatedly in our textbook each time a chemical is oxidized. For more examples of physical and chemical substance properties see the map in figure 1. 1. Physical properties are quiet simple to calculate. Determining the solubility or boiling point of a chemical for example is pretty cut and dry. I think this is most likely due to the fact that physical changes do not alter the identity of a substance. Chemical changes, in my opinion, are not as easy to recognize as physical changes. Chemical changes are determined by how a substance reacts with one or more substances when forming compounds. These reactions are known as chemical reactions. (Plaster, Soil Science pg. 13) Not all chemicals will react when mixed with another chemical; while some chemicals can be explosive or toxic when mixed with other chemicals. In previous science courses (soil science and chemistry), and in every day life, I have learned there are â€Å"observable clues† that can be used as indicators of a chemical change. When I drop an Emergent-C tab into a glass of water it reacts by fizzing or bubbling quickly until dissolved. The bubbles are created from gas production. It drives me nuts when a restaurant offers Splenda instead of Sweet-n-Low as a sugar substitute because Splenda doesn’t completely dissolve (insoluble) decaffeinated iced tea. Some Splenda will remain suspended in my glass while some settles in the bottom of my glass. The tea and Splenda formed a compound, but the insoluble Splenda is called a precipitate or a double replacement reaction. (Brown, pg. 47) Ever mixed two clear chemicals together and the compound magically turned a different color. I learned quickly, during a lab about reactions in aqueous solutions last semester that a color change can be a good indicator of a chemical reaction. Prior to beginning my chemistry labs this semester I watched a Lab Paq safety video. The Lab Paq host reminded me that chemicals can react to absorb or give off heat. Temperature changes are classified as exothermic, heat/energy releasing or endothermic, heat/energy absorbing and are both chemical reactions.

Calculations/Errors Before beginning my chemical changes exercise I tried to determine the chemical changes and reaction products.

I observed double replacement reaction, precipitation reaction, reactions between various chemicals with Bromothymol Blue and Phenolphthalein (acid/base indicators). In the e-text book, Chemistry: The Central Science (Twelfth Edition) , I learned about properties of acids and bases in chapter 4. I was able to use what I learned to aid in understanding what I observed chemically during this exercise. BTB or Bromothymol Blue (acid/base indicators – by color) Acids turned orange with a hint of yellow at the start of the reaction. Bases turned dark blue. Phenolphthalein (acid/base indicator – by color or lack of) Neutral and acidic solutions had no chemical reaction (color change) when combined with the phenolphthalein. Bases on the other hand turned as pink as a radish. Rate of Reaction I’m curious as to way some reactions take so much longer than others. I wonder if it has something to do with how strong of an acid or base it is, or something to do electromagnetic attraction of anions and cations, maybe solubility plays a big role. I’m uncertain what factor or factors determine the rate at which a reaction takes place, but I’d be an interesting topic to look into Knowing the rate of a reaction can aid in maintaining safety or enable one to speed up or slow down a desired reaction. I am now wondering all the possible benefits of knowing the rate of a reaction when it comes to soil and water remediation. Hmmmm†¦ Most importantly, I learned more about physical and chemical changes that could aid in the identification of unknown substances. I was able to practice the scientific method, write and predict chemical equations, get better acquainted with ionic charges (cations and anions), enforce what I learned in chapter 3 about replacement reactions, precipitates and more. I experienced first-hand the indicators that signal a chemical reaction is taking place (e. g. : gas evolution, heat/energy change, color change, and precipitate reaction). IX. Questions A. I could test for the presence of sodium hydrogen carbonate (sodium bicarbonate) in a household product by repeating one of test conducted early in the lab and comparing results. Test: 1. Place 2 pipet drops of the household cleaner into one well. 2. Add 2 drops of HCl (hydrochloric acid) into the same well. 3. Observe, waft smell, record 3. If bubbles are produced then CO2 gas was created and if a Clorox bleach smell is produced then I would assume sodium bicarbonate is present in the cleaner B. Phenolphthalein remains clear when testing an acid or a pH neutral substance and pinkish-red when testing a base. Bromothymol blue turns yellow when testing an acid, green when pH is neutral and blue when testing a base. I tested the household cleaning chemicals below, recorded my observations, and recorded my interpretation of the results. Data Table 2: Reactions Observed Well # Chemical Reaction Interpretation A 12 Windex BTB Dark blue in color, no precip. Windex is basic B 12 Dish Soap BTB Bright yellow color, Dish soap is surprisingly acidic C 12 Lysol Pheno. Light pink color, no precipitate Lysol is basic C. Suppose I found a sample of solution with a faint odor resembling vinegar. I then decided to verify the presence of vinegar by adding a few drops of phenolphthalein. The sample turned pink. I could assume the odor may resemble vinegar, but the sample does not contain vinegar. Vinegar is an acid. In earlier test, only bases turned pinkish-red when mixed with phenolphthalein. D. Using BTB (bromothymol blue), I selected five flavors of the new wave Vitamin Water to test their claimed pH neutrality. Three of the flavor-samples turn a murkey green when combined with BTB, indicating the likelyhood of acid/base (neutral) balance. Of the two remaining samples, one turns slightly yellow when combined with BTB, indicating the pH is most likely 6. 0 or slightly lower and more acidic then the first three samples. The fifth and final sample tested remained blue when combined with BTB, indicating the pH is 7. 6 or higher and is more basic then the first three samples. E. I devised the simple test below to confirm the presence of lead (Pb, an ingredient in Grecian Formula) in a new brand of hair tonic. Test To test the tonic for lead (Pb) I would combined a sample of Pb with potassium iodine (an acid). KI and Pb() react to form a precipitate when combined. If the hair tonic and potassium iodine react to form a bright yellow precipitate I could assume the tonic does indead contain lead. Background Knowledge (Includes: lead, aqueous reactions, precipitate, solubility, replacement reaction) Chemical Equation Pb(NO3)2(aq) + 2KI(aq) PbI2(s) + 2KNO3(aq) Double Replacement Reaction Pb2+(NO3-)2(aq) + 2K+I-(aq) Pb2+I-2(s) + 2K+NO3-(aq) Atoms like to have full valence (outer) electron shells with eight electrons. Depending on how full the valence shell of an element is determines its ability to attract another atom’s electrons. Ions are charged atoms which have lost or gained electrons. Cations are positive charged ions. While negative charged atoms are called anions. Ever heard the saying, â€Å"opposites attract†? Well, the saying is true in chemical reactions. The reaction between lead nitrate and potassium iodine is a double replacement reactions, Meaning the oppositely charged cations and anions â€Å"switch partners†. Net Ionic Equation Pb(NO3)2(aq) + 2KI(aq) PbI2(s) Group one potassium (K), iodine (I), and nitrates (NO3) are soluble in aqueous solutions. Lead (Pb) is soluble with Nitrates (NO3). However, Lead (Pb) is a not soluble with any group 17 elements (F-, Cl-, Br-, I-, and At-). Therefore, two soluble reactants combined to form one insoluble product: a solid bright yellow precipitate. G. During this lab exercise I allowed the chemicals NH3 and CuSO4 to react. The reaction produced a dark blue precipitate known as tetramminecopper(II) sulfate. The ammonia fumes have been known to waft from animal excrement and interact with nearby copper ammunition cartridges, damaginh the casing. Suppose a sample of this metal casing was collected from the site for analysis A researcher recorded the mass of a graduated cylinder filled with 10. 0 mL of water as 14. 1 g. (1mL = 1cm3 = 1g for pure H2O) Volume of H2O: 10. 0 mLMass of Graduated Cylinder: 4. 1 g She placed a chunk of the metal casing into the cylinder and recorded the volume as 11. 4 mL, its mass increased to 16. 6 g. Volume of metal chunk: 1. 4 mLMass of metal chunk: 2. 5 g Density = Mass/Volume or D= m/V in g/cm3 or g/mL D = 2. 5 g/1. 4 mL D = 1. 79 g/mL The density of the metal chunk is 1. 79 g/mL. H. Two pipette drops of each liquid in the table below were allowed to react for one minute. After reviewing the data recorded I can assume the unknown is NH3. I came to this conclusion because the unknown turned pale pink in phenolphthalein an indication it is a base with a pH above 7. 6. The unknown didn’t react with NaHCO3 indicating the substance must be soluble and relatively basic. The student could confirm their choice by testing the unknowns response to CuSO4. If the solution changes to baby blue and a cloudy precipitate forms then the student could assume the unknown is indeed CuSO4. Unknown Phenolphthalein The phenolphthalein turned the unknown pale pink. NaHCO3 No reaction seen Pb(NO3)2 White solid (precipitate formed) AgNO3 Nothing happened I. This lab exercise allowed me to observe several chemical and physical changes. It also improved my ability to recognize the difference between chemical and physical changes. Below I identified and explained some chemical and physical changes.
