Chemistry Essay

What is a Periodic Table and what is it used for in science and our everyday lives? On entering the chemistry laboratory at Mercer University, for Science 100 a large colorful chart displaying rows and columns of cells, was hanging over the chalkboard. I immediately felt a bit intimidated and my heart began racing. I questioned myself as to what am I about to experience? Moving closer to examine the chart, I felt as if the bright colors on the chart were generating warmth (energy) and…

in every class but I dedicated the most time and effort for AP Chemistry class. Besides waking up early in the morning to start off the day with solving chemistry problems, I also went to class during lunch to finish labs or to clean up after the labs. At home after finishing assignments for other classes, I sat down to get ready to tackle chemistry problems for at least an hour. I continued to dedicate so much time for AP chemistry class because of the rewarding feeling of accomplishment after…

Ref: Saunders N. 2000, Creative Chemistry You have seen that the Group 1 alkali metal elements increase in reactivity as you go down the group. Sodium is less reactive than potassium, which is less reactive than rubidium (which you weren’t allowed to observe directly!) Today, you will use displacement reactions to work out the order of reactivity of the Group 17 halogen elements using chlorine, bromine and iodine. Hypothesis: The higher on the periodic table the more reactive the element…

the bases and acids in my head to figure out what this lab meant exactly in my AP Chemistry class. Science has always fascinated me but when I decided to take this course, it was a whole new level. My chemistry teacher told me this course would be a challenge and it wasn't until I was in the course, that I realized he was completely right. Sure it was a challenge, but it was also fascinating to understand the chemistry behind all that exists and knowing that every single object is made up of…

Extraction was the main method of removing compounds from the sample. The component X was removed from the sample by first adding the organic solvent dichloromethane to the test tube. After aggravation, the component X dissolved into the solvent. Since components Y and Z were insoluble in the organic solvent they remained as solids. The test tube was then placed into a centrifuge and ran for thirty seconds. By doing so, the unsettled solid were forced to accumulate at the bottom of the test tube…

molecular etiology of various diseases and mechanism of drug actions. That builds my interest to achieve cutting-edge knowledge in biological chemistry to delve the physicochemical process,…

Chemistry is one of the most important and interesting categories of science. A chemist is someone who does research in the science of chemistry (Webster). It is an important job that requires many skills, including conducting research in order to obtain qualitative and quantitative chemical analyses, which can lead to the development of new products or knowledge (Occupational Employment Statistics, May 2013). Out of the many jobs in various scientific fields, a job as a chemist is one of the…

Chemistry plays a vital role in everyday life even though it may not seem like it. One of these things include firearms, which exhibits chemistry throughout the whole entire process. They show chemical and physical properties ranging from the gunpowder to the actual process of firing a bullet. Gunpowder is what makes the whole reaction occur. Without the use of chemistry throughout a firearm, would make it useless and it wouldn't work. These uses of chemistry occurs so fast that you may not…

Energy needed for life comes from the breaking or forming of chemical bonds during chemical reactions. Energy is released in the formation of bonds and energy is also released when the bonds are broken, but in both energy is required to start the chemical reaction. This energy needed to start a chemical reaction, activation energy, comes from enzymes. Enzymes (almost always proteins) are organic catalysts that help speed up the rate of reactions and allow the reactants to get the most out of the…

Pursuing a career in the chemistry field has been one of my dreams ever since I fell in love with the subject in high school. I love the challenge, knowledge, and determination that is required to obtain a chemistry degree; and the formulas and statistics it involves. There are different types of jobs in the chemistry field, but I decided I want to become an organic chemist researcher. The duties a chemist typically follows are research projects, testing and analyzing components, writing…
