Chemistry Essay

look forward to going to chemistry and understanding what we are learning. Chemistry continues to be fun even though there are sometimes challenges of not understanding it or getting confused. The labs in the classroom are incredibly interesting and never fail to amaze me I chose to pursue higher level coursework by taking AP Chemistry although it is challenging, I do not regret taking it. It showed me how rigorous and fascinating it is to learn about this science. Chemistry opened the door to a…

Chemistry is a branch of science that deals with the identification of the substances of which matter is composed. It also involves the properties and the ways in which they interact, combine, and change. Chemistry is important to life. The environment is composed of many chemicals without identification of chemicals we wouldn’t know what chemicals are safe to have around or which chemicals are harmful and dangerous to our bodies. To answer the enduring question, how do we gain knowledge to…

Activity 2: Chemistry In a Bag With Chemistry In a Bag, students learn the difference between a physical change and a chemical change and how changes can either be endothermic or exothermic. Set-up: Each group of four students will need 1 canister filled with calcium chloride (CaCl2), 1 canister filled with sodium bicarbonate (NaHCO3), 1 dropper of phenol red, a set of measuring spoons, a measuring cup, a portion cup, four pairs of goggles and four sandwich bags. Make sure there are paper…

Of the most abundant elements together 98 percent of the 8 elements form the mass of the earth’s crust, ocean and atmosphere. Two of the most abundant elements of the eight are calcium and magnesium. Calcium and magnesium are located on the periodic table located both in group 2 sharing the same family meaning that they share chemical property’s as well as the same valence electron because of their location and family relation to the period table. The alkaline metals are a reactive group of…

Background research: Redox reactions includes the two reactions called oxidation and reduction. Oxidation is defined as the loss of electrons, loss of hydrogen and gain of oxygen. Reduction, on the other hand, is defined as the gain of electrons, gain of hydrogen and loss of oxygen. Oxidation occurs when there is an increase in oxidation numbers and reduction occurs when there is a decrease in oxidation numbers. Oxidation numbers are values assigned to an atom in a compound which measures the…

“Alchemy was the beginning of chemistry. It is part of the history of science, which is the history of human interaction with nature, and humanity's attempts to harness the power of nature for very human needs and wants” (“The Magic and Myth of Alchemy”). Alchemists acted on the idea that nature had secrets to give and that it could be exposed through laboratory examination and experimentation. Regardless of their limited knowledge at the time, the work that the alchemists did provided the basis…

Hey Mom, I know you’re dying to know how my semester is going so I thought I’d share with you some of the assignments I’ve been working on. I just finished my first chemistry lab project involving drugs! Yes, drugs, but not the ones you’re thinking about. We worked with Sulfanilamide, Phenacetin, Acetaminophen, and your favorite, Caffeine. The goal for the experiment was to determine where the drugs may reside according to their properties. We learned that there are parts in the cell that are…

The learning assistants for Professor Bahde’s Organic Chemistry I class, Allyson Dang and I, wanted to give the students a problem to work on involving a reaction mechanism. The students in that class have been struggling in many areas of the subject, but the main issue they have is drawing out reaction mechanisms. Knowing how to draw out reaction mechanisms is one of the most, if not the most important part of organic chemistry. When theoretically reacting molecules, one must know not only…

I request to take AP Chemistry because I want to major in Biomedical Engineering. By taking AP Chemistry, I will be a step closer for preparation of my future profession. This year as a sophomore I am taking AP Biology, AP Psychology, Honors Pre-Calculus, Physics 1, and Chemistry 1 simultaneously without any issues or problems. I also have taken AP United States History as a freshman along with seven other courses. Because of this, I understand the demanding nature of these AP courses and the…

contains is held together by one thing: chemistry. Chemistry plays an important role in all of our lives due to this fact. Whether in my career or in everyday events, chemistry will be an unseen, yet central, influence in my life. This is apparent in both my personal activities when baking, wearing clothing, participation in holiday traditions and my professional life when writing software, creating biological implants, engaging in computational chemistry and in the creation of the hardware I…
