Single displacement reaction

Bob went back to his desk, grabbed the remaining bottle of hydrochloric acid and proceeded to dump it on the lock, which promptly melted away; Bob resolved never to touch the acid directly with his hand. In the drawer, he found a single small circular blue rock. Only one inch in diameter, the blue rock seemed to be glowing faintly. Bob picked it up, and walked back to the Gatorade bottle on his desk. Without giving it a second thought, he dropped the rock into his blue…

difference between compounds and elements, and to determine the difference between complete and incomplete reactions. Previous chapters that contained valuable background knowledge were Chapter 2: Mass Changes in Closed Systems and Chapter 5: The Separation of Mixtures. The Law of Conservation of Mass, which was tested in Chapter 2, proved to be vital in this chapter by helping groups understand the reactions that the group could not necessarily see, but could be verified by this law, such as a…

proteins that act as biological catalysts. A catalyst can be defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Enzymes are essential due to the fact that virtually every metabolic reaction which takes place within a living organism is catalyzed by an enzyme. This is because organisms catalyze the chemical reactions that would otherwise not be able to progress under typical physiological conditions, such as because they…

The Effect of Temperatures on Rate of Reaction of Alka-Seltzer Introduction: A. Background This particular experiment consists of a purpose of finding out the effect of various temperatures on the rate of reaction of the Alka-Seltzer tablets. Alka-Seltzer is a medical drug that acts as a pain reliever or an antacid, which helps neutralize stomach acidity, such as heartburn. Alka-Seltzer is a form of a baking soda which is also known as sodium bicarbonate, (NaHCO₃). When sodium bicarbonate…

For this experiment, a few scientists are researching how different flavors/colors of sports drinks effect the amount of red 40 dye in each drink. The independent variable in the experiment is the flavors of Gatorade (a brand of sports drinks) used, while the dependent variable is the concentration of dye the sports drinks contain. The constant variable is the spectrophotometer, the amount of liquid used, and the same type of cuvette. The controlled variable is only using water. In order to…

030 Abstract In order to turn hydrogen peroxide into water and oxygen by using enzyme called a catalyst. To determine the effects of temperature and substrate concentrations we preformed an experiment testing the effects on the catalyst enzyme reaction. The hypothesis for our first experiment was if the substrate concentration is larger than the catalyst enzymes activity will be faster as well. The result followed suit with our first experiment and supported our hypothesis. The hypothesis for…

This experiment is to be used to determine the era of which the composition and thus the density of the penny changed, and what the other metal besides copper has made up the composition since 1962. First, ten pennies from three different time periods (1995-1999, 2000-2004, 2005-present) were gathered. All ten pennies from a specific time were weighed together on an analytical balance. Then, a fifty mL graduated cylinder was filled with twenty mL of water, which was recorded as the initial…

Synthesis of oleyl 9,(12)-hydroxy-10,(13)-oleioxyoctadecanoate (OLHYOODT) (4) The reaction mixture was heated on a magnetic heater and stirrer until it reached the experiment temperature; catalyst sulfuric acid (SA) and desiccant of silica gel (SG) were added to the mixture at that moment to remove the water during the reaction. The reaction temperatures were held constant within a range of ±1°C. A mixture of HYOODA 3 (5 g; 0.01 mol), oleyl alcohol (OL) (10 g; 0.02 mol) in a 250-mL three-neck…

nitrotyrosine is being recognized as a crucial independent marker of cardiovascular disease (Peluffo et al. 2007). Our primary goal for this experiment was to synthesize, purify, and identify p-nitroacetanilide. First, we performed a series of chemical reactions to yield our desired product. Then, to test for purity and to furthermore scrutinize the molecular of our desired product, we used Gas Chromatography-Mass Spectroscopy (GC-MS), Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy,…

A. i) The rate of a reaction is the change of a substance’s concentration per units of time. The reaction rate of an experiment is dependent on many things including concentration, presence of a catalyst, and, most importantly, temperature. Temperature and reaction rate are directly correlated, which means that as one increases, so does the other. It is a general approximation that the rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature…
