...(name withheld) November 13, 2014 Prof. (name withheld) LABORATORY EXERCISE ON GREEN CHEMISTRY Although not as much as in the past, pollution still continues to impact our environment negatively. The formation of the Pollution Prevention Act of 1990’s goal to clean and fix the problems caused by pollution and later started the green chemistry movement. The aim of this movement is to prevent pollution from the start rather than fix it later or even dealing with the disposal and clean up. Industrial power plants for example are polluting the air with toxic smog. China is one such example facing this very problem which created too much air pollution that their city is covered in smog. The situation is so dire the citizens live in an environment where one cannot walk out their door without the use of a face mask. They are now in a situation where they are trying to come up with solutions to solve the issues they are currently facing. Had they practiced any form of green chemistry, this could situation would have never happened in the first place. Such a situation is the reason why we should strive to further advance the science of green chemistry. If everyone start using and putting some if not all of the 12 principles of green chemistry into practice, less hazardous material or safer industrial process should circulate more easily. If air pollution is itself can be prevented, the people wouldn’t have to worry about the dangers of breathing toxic air every time they...

Image that you could travel back in time and found yourself in a small European village in 1392. What do you think you would find? How would you cook your food? Would you use an oven, a fire, or a microwave? How would you eat your food? Do you think you could use a plastic cup to drink your milk? How would you go from one city to the next? Could you get on a train or would you have to walk or ride a horse? How would you send a her or call her on your cell phone? message to your mom telling her you’ll be late for dinner?

...Chemistry and Society (Name) CHM/110 Due Date Instructor Chemistry and Society Chemistry is an important part of our society. It is used for manufacturing the products we use, medicine, and just about every other aspect of our lives. This document will discuss how society depends on the accuracy and precision of measurements, the difference between accuracy and precision, and compare and contrast accuracy and precision of different types of measurements used in our daily lives. Accuracy and Precision Since the bulk of this discussion is about measurements, we will start off by discussing the difference between accuracy and precision in that context. When making any kind of a measurement, we need to be able to get as close as we can to any certain number. The question often asked is, how close to the actual number can we get? If we can get close that number that would be considered accuracy. When we think about precision, it is a different concept. Once we have been as accurate as we can be with our measurement, precision would be how many times we can achieve that measurement. Can it be duplicated? Society Dependence on Accuracy and Precision When we think about all of products available in the open market, we, as consumers, expect consistency in the products we buy on a regular basis. For example, Diet Coke is product a lot of us love to consume on a regular basis. We expect that soft drink to have a certain taste and not be flat. If we were to buy it...

...“Chemistry is a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo” (Merriam-Webster. 2011). Thus saying, Chemistry is a major influence on our lives on a daily basis. You find it by the air that you breathe in, the food that you eat, and every object that you can see or touch is a fundamental of Chemistry. Throughout this paper, I will describe why chemistry is important, what is beneficial, and what I found interesting. In order for me to purse my degree in Chemical Engineering, it was a must for me to take Chemistry 1411. First, it was a pre-requisite for the following Chemistry classes for me to take. Second, the basis of this class is a fundamental pertaining to my degree because they have to apply the principles of chemistry to design and operation of immense chemical manufacturing process. I chose this major because my grandfather inspired me from such a young age to be in this field. I can remember him doing all kinds of experiments in his office trying to test and discover things that really drew my interest to this major. My grandfather demonstrated the benefits of Chemistry and showed me how it is ever present in our every day life. He also taught me that Chemistry is always changing in our world around us and I want to be apart of this changing process and help the world benefit from Chemistry. I hope to see myself in a couple years being highly successful and enjoying working for a refinery...

Introduction Working in the medical field can be a rewarding experience, when you see the patients feeling better, returning to the comfort of their homes and life as they know it. However, it can also have its challenges. I work in a medical lab at a children’s hospital and within the lab we have departments consisting of support staff (phlebotomy, specimen processing, and reference lab), chemistry, hematology, coagulation, microbiology, pathology, histology, flow cytometry, blood bank and research. Knowing that the majority of our patients treatments are based on their lab results, we have to all work together as a core lab (a team of one) in order to get our patients results out in an efficient and timely manner. “The team concept implies a shared mission and collective responsibility” (Gafa, Fenech, Scerri & Price, 2005). But because we have such poor team work within the various lab departments, there is usually a delay in getting results out in a timely manner. This affects our turnaround time and most importantly patient care. So if I could change...

...Chemistry and Society Accuracy and precision are two critical factors to contemplate when performing a measurements of data. Both accuracy and precision indicate how a measurement is close to a definite value. Accuracy reflects how close a measurement is to an identified assessment or accepted value while precision produces how measurements are recalled, even if they are distant from the accepted value. (Helmenstine, 2014) Precision also refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the agreement between experimental data and a known value. (Helmenstine, 2014) Chemistry and Society Accuracy and precision are important conceptions, and how they relate to an experimental measurement. By using scientific notation the concepts of precision and accuracy can be accomplished in a simpler matter. Precision and accuracy can be in hitting a bulls-eye of a target. If you hit the target accurately implies you are close to the center of the target even when the marks are on different sides of the center of the bulls-eye. If you hit the target precisely means all the hits you made are spaced closely, but still far from the center of the bulls-eye. (Helmenstine, 2014) Our society is depending on the precision and accuracy when measuring products we purchase every day. Precision and accuracy goes hand in hand together to make proficient measurements. If a product is not measured correctly, it would not have the same effect...

After 2 months of sweltering heat in the White House, he was not doing well and they prepared a train to take him to the Jersey shore for cooler weather and better views. They knew he was in bad shape. They created a special train that burned "cleaner Anthrocyte coal" to avoid getting pollution into his infected wounds. In the 1880s we realized that pollutions were bad for sick people. Now, we know that this may actually be partially responsible for some of the illnesses in the world.

... and although organizations are not people, they are made up of people. What happens within an organization affects the people in and around it, people spend a very large part of their lives working for or with an organization so it's best to remove and limit any problems whenever possible. One problem is that many organizations seem to lack trust, this can be seen whenever there is a big scandal within an organization or many employees leave expectantly because of one reason or another. "People also resist change when they do not understand its implications and perceive that it might cost them much more than they will gain. Such situations often occur when trust is lacking between the person initiating the change and the employees" (Kotter 33). When employees distrust their leaders, it breaks the unity and effectiveness of an organization. This could be within a church, a non-profit, a Walmart, or anything else, but it will always affect the end product, or the goal of the company at some point down the line. I think another issue within organizations is a lack of principles. I love this line in Principle Centered Leadership, "principles are self-evident, self-validating natural laws. They don't change or shift. They provide 'true...

...Atoms, Molecules, and Elements Michelle Faunce-Carroll CHM/110 - INTRODUCTORY CHEMISTRY BSDT1HX1M4 WILLIAM DE VORICK AUGUST 10, 2015 Atoms, Molecules, and Elements Atoms, Molecules, and Elements are a part of everything we do in life. Most people don’t recognize the extent that chemistry plays in our everyday lives. From the foods we eat, to the products we use for cleaning ourselves, our homes, our cars; atoms, molecules, and elements are a part of all of these things. Dmitri Mendeleev began studying elements in the early 1800’s. Through his learnings he found that elements are sortable, have similar properties, and are even predictable. In addition to this his research also led to his coming up with the periodic table. Thanks to Dmitri Mendeleev we can now know the way molecules are formed. Because of this we know the charge of the elements, which in turn helps us to know how they will react with each other when combined, we are able to predict if this will be a good or bad reaction. Grouping elements into families was first taught by Dmitri Mendeleev. He began by studying their atomic weight, charge, and reactivity. And then grouping the elements with similar properties within the same family. Within these families we can look at how they would react with other elements on the periodic table. Take hydrogen for example when this is paired with oxygen to form H2O, you have to have 2 hydrogen...

...To become happier and more successful, part of the process is to consciously work on increasing the chemistry of your cranial fluid so your brain can perform more efficiently and at higher levels. You can increase your natural abilities and happiness by consciously adjusting the chemistry of your brain's cranial fluid which is affected by your thoughts, diet/nutrition, exercise, rest, environment and physiology. Since your thoughts have the biggest impact on the brains chemistry, there’s where I’m going to focus. When you have positive thoughts, your brain secretes positive chemicals and increases the power of your brain. When you have negative thoughts, your brain secretes negative chemicals and decreases the power of your brain. This is a simple, but profound concept to realize. Happiness depends on it. Your thoughts from outside stimuli have two components: facts and emotions. While you may not be able to control the facts you encounter in your life, you can choose how to respond emotionally to these facts. If you choose positive emotions, you will be happy. If you choose negative emotions, you will become unhappy. Your happiness depends on what emotions you choose to experience and how you live your life. For becoming happy in relative thinking there are no general rules. Happiness means nothing more than feeling well as result of an action, the deep experience of something being alright. This feeling completely depends on what is considered by happiness...

... The Abilities of an American Inventor At first glance it appears as though Philo Farnsworth, at a very young age, developed a natural ability to understand complicated concepts. At 14 years of age, Philo envisioned a way to create the all electronic television. Later, at 21, he was able, with the help of his wife and her brother, to build all the components, and assemble the first television. The time in between these two events seems to point to something other than just technical ability. Philo was able to create and also recognize opportunities. To most people, this may be more important. Most people will probably not invent anything at all, let alone something that has had the impact on our lives that television has, but we can all look back on our lives, and see opportunity that we have missed, or maybe a time we did not put forth the effort we should have. Philo’s ability to seize an opportunity is something we can all learn to achieve (Encyclopedia of World Biography, Thomas Gale, Edition 1, 1998). Philo Farnsworth was born in Indian Creek, near Beaver Utah, on August 19th, 1906. There was no electricity where Philo lived. Philo’s father, Lewis Farnsworth, would often discuss the technical aspects of such devices as the telephone, gramophone, and locomotives with his son. Philo also would read technical and radio magazines. When the family moved to a farm in Idaho that had it own power plant, Philo took the opportunity to study the plant, and...

...road to survival seemed impossible and unachievable. Throughout the narrative, Primo transforms from an apathetic victim to a progressive survivor in the German concentration camp at Auschwitz. The concept of black marketing, knowledge in chemistry and his spirituality all contributed toward the survival of Primo Levi and others in Auschwitz. According to Primo Levi, illegality, deceit, infidelity and sin were all relevant in the concentration camp. These characteristics made up Auschwitz and were used as necessities in order to survive such horrid conditions. Those who were captured and sent to German camps quickly noticed that this was a place where happiness was extinct. Little pieces of bread, shoes or soup bowls were perceived as rather large when consumed and used by other prisoners. The smallest amount of food attracted any inmates, creating trust issues and this idea of every man for himself. This type of nature constructed the black market and how it was used amongst Levi and others as a survival tactic. This encouraged prisoners to deceive and steal food or property for their personal gain. In order to survive inside the death camp, Levi explains how one learned to cope with the environment and do whatever they could to live. Primo...

...The Process of Digestion Over the course of time there have been many difficult questions and theories about everyday life. Using physiology & chemistry, those questions have been able to be answered. From the mixture of gases in the air we breathe to the organic substance of plastic or paper, chemistry can be seen everywhere. However, most people mistook the power of chemistry in our own bodies. How is it that a simple slice of bread, once consumed, can turn into fuel for the human body? Using the digestive system and its many organs through the process of digestion and metabolism is how our bodies receive the energy it needs to continue on throughout the day and the rest of our lives. Chemistry then kicks in as food starts its process from entering to leaving the body, through the rate of our metabolism, and also by the transfer of energy. The chemistry in the digestive system is a very important process, because without it there would be no human life. Compared to all other systems in the body, the digestive system is one of the most diverse and important. According to Robert Sullivan the digestive system is a set group of organs whose function is based on the process of turning food, absorbing nutrients for energy and getting rid of the bodies waste (Sullivan, 2008, p.33). The organs that are in the digestive system are the following: esophagus, stomach, small intestine, pancreas, liver, gallbladder, colon or large intestine, rectum and anus (Ballard...
