...At first, I was in the Integrated Track when I first changed my major from Pre- Nursing into Liberal Studies. After taking the HUM 197 I was able to see the benefits of both tracks and decided to go with the General Track with a concentration in Chemistry. Even though Integrated track saves me money, the General Track allows me to be finish Summer 2018 which gives me more time to take the CSET part by part instead of taking it all at once and not being able to get into the credentials because I have not yet pass my CSET. By choosing the General Track I have time to just focus on my classes that I have left this year and have the opportunity to get a job as a substitute teacher. I have already taking the CBEST therefore I will have the summer...

...gave a very interesting presention on computational chemistry. This presentation allowed us to see a different side of the molecular approach. He explained thoroughly the modeling of chemical reactions. This modeling of chemical reactions saves time and allows researches to study in detail structures of an atom or molecule that can only be done by computer. There are different types of modeling reactions that are comparable. Homodesmic equations in particlar is one excellent way to determine strain energies. There are different types of strain. Baeyer strain, stretching or compression strain, Pitzer strain, and Dunitz Shomaker strain are examples. Many studies revolve around cyclopropane and cyclobutane strain energies. Dr. Magers explained why these two types of strain in particular are similar. He also went on to explain the method for calculating and interpreting strain energies in a chemical equation. The presentation went on to support computational details of strain energies. Azetidine and phosphetane are computed within homodesmic, isodesmic, and the hyperhomodesmic models. Model equations allowed us insight into computational details of these strain energies. Results of the strains were included to showcase different results yielded through computational chemistry. Computation of gas phase enthalpies was included to further testify to the importance of computational chemistry. Computational chemistry provides a very unique way of calculating thermodynamic...

...What is Biochemistry and why you should study it? Biochemistry or sometimes we called it as biological chemistry is defined as a scientific study of the chemistry of living organisms, especially the structure, the behavior of a living thing and the function of their chemical component such as proteins ,carbohydrates, lipids, and nucleic acids. Many of these molecules are complex molecules called polymers, which are made up of monomer subunits. Most people consider biochemistry to be same with molecular biology. Nowadays, biochemistry has become the root for understanding all biological processes. It has provided widely explanations for the causes of many diseases in humans, animals and plants. As a student, we should study it because it give to us many kind of knowledge on understanding the biological processes which are happen around us in every single minutes in our life. Since biochemistry is very important, we must study it to know how this biochemistry contributed for the sustainable of tomorrow in the main field of medicine, agriculture and industry. Biochemistry is applied in many health field such as dentistry, medicine and veterinary medicine. For example, in the field of medicine, biochemistry have contribute in the clinical study to maintain and to give a better and healthy life to the population of human all around the world. This have been done by the scientist on how they use biochemistry to diagnose and control the spreading of diseases, product a new...

...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...

...those moments for granted. Three years later, and we still lay under those bright majestic stars hoping that we will always still love each other, even if I never see his face again. The first time I met Alex you could tell there was chemistry between us and three years later, I still get an igniting spark with the exception of knowing how love actually feels. At the beginning of a relationship you become infatuated and as time goes on it turns into love. Infatuation becomes the start of a relationship when that spark ignites and to yourself you want this person next to your side for the rest of your life, or so you think you do. It can become almost a sexual desire for one another. Butterflies flutter inside your stomach and the inside of you becomes so weak you just think you’re falling hopelessly in love. There’s a profound chemistry that starts at the beginning of a relationship and within that time you become inseparable. Your friends no longer exist, and all that comes to your mind is this wonderful emotion about being with this amazing person. During the infatuation stage, public display of affection is a primary key. Being in love you don’t care what people think or say about your relationship. Most relationships during infatuation revolve around PDA, like the first time he holds your hand, or when he pulls you in so close to lay his lips on yours, and when you hug each other you can hear your heart’s pounding in sync. It’s that sexual desire for each other that pulls each...

...Lab Report Chemistry 341L: Preparation of Cyclohexene Introduction: The purpose of this lab was to prepare an alkene, cyclohexene, by the dehydration of an alcohol, cyclohexanol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene, using phosphoric acid as a catalyst. Unsaturation tests are then done to ensure cyclohexene was prepared. Experimental Scheme: The procedure for the Preparation of Cyclohexene lab started with first having to add 10mL of cylcohexanol (clear liquid with strong odor), and 2.5mL of phosphoric acid (clear liquid) to a 50-mL round bottom flask. These liquids were mixed together well; a boiling stone was added to the flask in order to allow for a smoother and gentle boil. Below is the equation for the reaction that took place in this lab. Equation 1: Formation of the product cyclohexene, from the reactant cyclohexanol with the aid of a catalyst phosphoric acid4 Next a distillation apparatus had to be assembled, using a 25-mL round bottom flask as a receiving flask, this flask was then placed into a beaker of ice water refer to figure 1. Figure 1: Distillation apparatus5 Distillation is used in order to dehydrate the cyclohexanol. After the apparatus was assembled we circulated the cooling water in the condenser, while heating the mixture in the flask. The flask was heated until the product started to distill, and collect into the receiving flask in the ice water bath. We continued to heat the mixture...

...1. Why are scientists interested in the possibility of life beyond Earth? The discovery of life of any kind beyond Earth would forever change our perspective on how we fit into the universe as a whole, and would teach us much more about life here on Earth. 2. People have long been interested in life beyond Earth. What is different today that makes this possibility seem scientifically reasonable? Today, technology has flourished and is more advanced than it was in the past. We are able to have telescopic and spacecraft photos of planets and large moons, as well as launching missions to further investigate our curiosity. Because of these advances in technology, we know more about the universe than we previously did. 3. What do we mean by a geocentric universe? In general terms, contrast a geocentric view of the universe with our modern view of the universe. Thousands of years ago, many people believed that the Earth was at the centre of the universe; this was the geocentric view. The geocentric view of the universe contrast our modern view of the universe since it is a Sun-centered view. 4. What are extrasolar planets? In what way does their discovery make it seem more reasonable to imagine finding life elsewhere? Extrasolar planets are planets orbiting stars other than our Sun. It is now more reasonable to imagine life elsewhere since many or most stars have planets. Therefore, there may possibly be life living on these planets or moons. 5. What do we mean...

...“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...

...The benefits of Chemistry in Computers It is obvious that computers are important in taking measurements but they can also be used to predict measurements. There is some very powerful software available for predicting physical properties of compounds. Bond lengths, melting points, vibrational frequencies and properties such as solubility can be predicted using dedicated software based on theories known. Software like this can help you to 'design' a molecule to the specific needs of the chemist. Without the software, it would take hours of calculations to predict the properties. Another important area of chemistry is analyzing data obtained from experiments, to look for patterns to prove theories. This can be done by hand, but involves a lot of calculations, which is time consuming and liable to mistakes. Analyzing data is often best done using a spreadsheet. Spreadsheets can quickly work out calculations and plot graphs showing a pictorial representation of the data more easily than any human could. Spreadsheets are usually very good at calculating the equation of a best-fit line of a graph, which is often important in chemistry. Having used computers to obtain accurate data, it seems sensible to store it where it can easily be retrieved for reference. It could be stored on paper, filed away in alphabetical order. This is fine until the chemist wants to find data on a group of compounds such as the alcohols, or those with a melting point of over 100oC. This is where storage...

...Chemistry and Society Paper Chemistry is all around from the air we breathe to the water we drink, most people are not thinking of chemicals, but natural substances. Chemistry explains how the properties and behavior of chemicals are composed of atoms and molecules. The agricultural industry uses this knowledge to determine weaknesses and strengths in the crops they grow to determine yields. For instance a farmer may be having a problem growing a certain crop due to a deficiency of a needed element. I work for a company that provides needed elements for this industry. Verdesian Life Sciences provides nutrient based products for farmers. Accuracy and precision are concepts of great value to be successful. The products we provide must be accurate and precise to our claims regarding the guarantee analysis. Accuracy is the degree of closeness to true value based on a single factor or measurement. Precision is the degree to which an instrument or process will repeat the same value based on multiple measurements. Example will be the guaranteed analysis of a product that provides nitrogen, phosphate and potassium. When you test the product you are testing for the accuracy of the claim, however the precision is the result of using the product multiple times. Scientific method is a series of steps to prove a theory based on analysis from an actual experiment. We start with a question and based on our knowledge we form a hypothesis for the best answer. To prove or disapprove the hypothesis...

...Lab Research Report 1: Procedures in the Physical Sciences Robert Hugee Professor Brian McCann SCI110024VA016-1134-001: Introduction To Physical Science April 25, 2013 One of the underlying challenges in astronomy measurement is the determination of precise distances. Without a knowledge of its distance, the size of an observed object in space would remain nothing more than an angular diameter, and the brightness of a star could not be converted into its true radiated power, or luminosity .astronomy. (2013). Direct measurement of the wavefunction had also long been deemed impossible because of the key tenet of the uncertainty principle. University of Rochester (2013, March 3). Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond those...

...The Chemistry behind a Cheeseburger The first cheeseburger was created between 1924 and 1926 by a 16 year old chef from Pasadena, California named Lionel Sternberger. The anecdote goes that a passing homeless man suggested Sternberger should add a slice of cheese to his hamburger order. Sternberger then added this to his main menu at the Rite Spot and the cheeseburger was born.1 Today the cheeseburger is marketed by not only fast food chains like Steak-N-Shake and McDonald’s but also steakhouses such as Longhorn and Logan’s Roadhouse. Whether you choose to cook your cheeseburgers at home on the grill or grab one on the go, cheeseburgers are an American tradition that everyone can enjoy. However, not all who devour this scrumptious piece of American history actually know the chemistry behind the ingredients that come together to make this delicious masterpiece. A cheeseburger would not exist without the bun to hold all of the ingredients together. The bun is made of flour, a starch or long chains of sugars molecules known as polysaccharides, yeast, salt and water. Flour, or grains are comprised mainly of wheat. When these ingredients mix, the flour gums up and absorbs all the water to produce a protein matrix called gluten. Gluten is elastic and holds the bread together to give it structure. As you knead the dough, the yeast, a living single cell creature, begins to eat the starch. When the starch is consumed by the yeast, carbon dioxide is produced. The process of microbes...
