Analysis of Galvanized Nails, Quality Control, and Green Chemistry Introduction: In this lab, we handled acidic chemicals that needed to be disposed of upon completion of the lab. We disposed of these chemicals according to safety policies and green chemistry policies. Green Chemistry is the practice of chemistry in an environmentally safe way to prevent pollution. We used green chemistry to minimize the amount of waste we were to be creating.…
Computers, cell phones, TVs, all this stuff, is just waiting to release all their toxics when we throw them away. Some of them are slowly releasing this stuff even while we are using them. You know those fat, old TVs that people are chucking for high-def flat screens? They each have about 5 pounds of lead in them. Lead!…
INTRODUCTION The purpose of this experiment was to demonstrate the stereochemistry of the electrophilic addition using (E)-Stilbene, a trans-isomer of ethylene. Bromine was added and reacted with (E)-Stilbene to form an alkene. A product was made with both a meso-stilbene dibromide and a d/l-stilbene dibromide, which is trans-stilbene dibromide. DISCUSSION AND CONCLUSION For the reaction to form these two different compounds with the same starting reactants, the double bond of (E)-Stilbene has to attack one bromide.…
Water is very important to the human body, but if it is contaminated, what is the replacement for water? In the city of Fruitvale, there was a leak in Strawberry Creek of No-Bug Pesticide. If No-Bug Pesticide gets to 5.0 ppb (parts per billion), the water is unable to drink. Therefore, I think that bioremediation is the best solution to clean up Strawberry Creek because it poses no health problems, you can fix conditions if they are improper, but the conditions are hard to get through. First off, bioremediation poses no health problems.…
The Berengarian government has recently put into place new environmental legislation, which holds electronic manufacturers responsible for the recycling of any toxic waste found in their products. This legislation outlines that the manufacturers are still legally responsible for the proper…
Chemistry is the field of science involving structures, composition, and properties of substances and matter in order learn how they interact with each other. However, disposing and making chemicals can cause hazard to the environment and wildlife. In “Chemistry: Green and Clean,” Jennifer Weeks builds an argument to persuade her audiences that green chemists are working cooperatively to develop a field of chemistry that can replace polluting technologies. Weeks uses alternative ways to effectively break down harmful chemicals, methods to break down endocrine disrupters and other chemicals in the environment, and techniques to prevent immense usage of water and energy to enhance the logic and persuasiveness of her argument. Chemicals have been used for thousands of years for different purposes.…
Harmful chemicals found in consumer products every year put humans and the environment at risk. Unfortunately you can’t just shop your way around the chemicals. Chemicals are found in more items then what one thinks. The article “Chemical in Plastic May Harm Children” by LA Times staff writer Marla Cone you learn that the chemicals found in plastic products can lead to harmful side effects. The chemical bisphenol A, or BPA was found to be harmful by The National Toxicology Program.…
Is Electrolysis Permanent? Yes, it is possible to remove hair permanently through electrolysis method. No other treatment for hair removal can guarantee like electrolysis. Removal of hair through the electrolysis method is safe and a permanent solution for stopping hair growth in your body.…
In today’s society people have become more involved in the criminal justice system than has been in the past. People felt that the use of electrocutions were inhumane in the past and were afraid to say so then, now that times have changed people still feel that the electric chair is inhumane but now they aren’t afraid to speak up for what they believe in. Lethal injection is being used more now because society feels that it’s a more humane method of execution. Although some states still use the practice of electrocution as a method of execution. Today it is used as a secondary method.…
Elements of Battery The law of torts is the compensation of losses suffered by private individuals in their legally protected interest through socially unreasonable conduct. Moreover, the law of torts seeks to protect bodily integrity and is actionable per se. Consider the following case of Moon v. Whitehead, the legal issue considered was consent in the tort of battery. Ms. Whitehead the respondent, plead that she retired to bed in an apartment she and the appellant were sharing in Sydney for the duration of an interstate work conference. The appellant came into her bedroom uninvited, without her consent and forced himself upon her.…
Lead and zinc are mostly present at the same occupational source, usually found as co-contaminants at specific sites and are among the top 10 substances found most frequently at national priorities list (NPL) sites with a completed exposure pathway.1 Lead has been known to humankind from ancient times and its use was increased immensely from 17th century onwards due to industrial revolution. Primarily lead was used in paints, ships, gasoline, pottery etc. However upon recognizing debilitated toxic potential of lead, its use was reduced from 20th century onwards. Though reductions in its use from late 20th century were recorded by removal of lead from gasoline, but due to the vast benefits and unique physical and chemical characteristics, its use were introduced into new things like batteries, grease, solders, smelting, tile factories etc.2 Zinc on other hand is essential trace element of living organisms and without it number of functions in body cannot occur. Zinc is an important ion of reaction centre in large number of enzymes and proteins.…
For years many individuals have fought to demonstrate the important of protecting our environment around the world. One of the main issues we face today is the effects of pesticides in the environment. These issues have now began to be noticed by experts and organizations because leaders such as Rachel Carson have brought them to light. Rachel Carson’s bestseller “Silent Spring”, describes various case where pesticides are dangerous and led to environment problems. Everything in our environment is related and affected by each other.…
In this experiment, various electrochemical cells were measured and calculated to determine their electrical cell potential. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (0.10 M) │ Cu(s), E cell potential was determined to be 1.040 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (1.0 M) │ Cu(s) E cell potential was determined to be 1.060 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Cu (s) │Cu2+ (0.010 M) ││ Cu2+ (1.0 M) │ Cu(s), E cell potential was determined to be 0.032 V while the standard E˚ cell potential was 0.00 V. The E cell value in the electrochemical cell Cu (s) │Cu2+ ( M ) ││ Cu2+ ( M) │ Cu(s) was determined…
The type of sauna in which light is created by heat it is known as infrared sauna. Traditionally it is used to warm the air, which results in giving warm to the body. It uses infrared heater which emits light of infrared which is absorbed by the skin. Detoxification:…
Introduction Electronic waste management can be referred to as electronic materials that are no longer in use, for example; computers, mobile phones, electronic equipment’s that are found in the office, refrigerators among others (Kahhat et al. 2008). These types of electronic are in most cases kept away for reselling, reusing, for recycle purposes and at times they are scheduled for disposal (Kahhat et al. 2008). Other types of electronic waste usually include re-usable electronics that are thrown away by the consumers since they no longer have any use for them. The buyer dumps them if they have been used for over a long period of time, and if they are recycled, the products obtained will be of no use at all (Song et al. 2015).…
