Chemistry Essay

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,…

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…

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…

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…

• A candy maker named, Hans Riegel started the Haribo candy company in 1920. In 1922, he created the dancing bear candy made of gum arabic. The dancing bear candy was larger than the modern gummy bear. Modern gummy bears come in five colors. They are red, clear, orange, green, and yellow. Modern gummy bears contain sugar, glucose syrup, starch, food coloring, citric acid, and gelatin. • Solutions are mixtures that are mixed evenly throughout and can not be separated. The solute is the…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

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…

furthered this interest inside and/or outside of the classroom.(prompt) For sure an academic subject that has inspired me has been chemistry. My sophomore year I began by taking the Honors Chemistry course offered at my school. The first couple of weeks proved challenging but I loved learning and applying this subject to my everyday life so much that I decided to take AP Chemistry my Junior year. Despite not having the highest grades in the class I can say with certainty that I had the greatest…

Alchemy was the earliest understanding of today’s chemistry. These two display Is Alchemy Chemistry? different pathways of thinking and rationalising rather than two diverse concepts. The practice of alchemy is the basis of chemistry, as it was a vital role of origin and evolution towards chemistry we know today. The comprehension of both alchemy and chemistry will aid in order to establish their connections and difference of opinion or belief. Discovering both histories of the two concepts will…
