Introduction: Within a cell, enzymes are used as a catalyst to increase the rate of chemical reaction. They do not consume themselves, rather they help in increasing the rate of reaction. Within the body, enzymes vary depending on their specific functions. For instance, hydrogen peroxide is a toxic chemical, but it breaks down into harmless oxygen and water. This reaction can be sped up using the enzyme catalyst produced by yeast. Hydrogen peroxide is produced as a byproduct in cellular reaction

1M hydrochloric acid solution to a small test tube. 2. Obtained a 2-3 cm strip of magnesium metal ribbon and coiled it loosely into a small ball. Added the magnesium metal to the acid in the test tube. 3. Carefully felt the sides of the test tube and observed the resulted chemical reaction for about 30 seconds. 4. While the reaction was still occurred, lighted a wood splint and quickly placed the burned splint in the mouth of the test tube. Do not put the burned splint into the acid solution. 5. Recorded

Arsenic contamination in groundwater has become a major health problem for human being. There are many treatment methods have been developed for arsenic removal. It is important to develop a treatment method that is economical and accessible for people who live in rural areas and cannot afford the expensive treatment methods. Due to its several advantages, such as low cost and maintenance, electrocoagulation is one of the promising methods that can be used for arsenic treatment. In this study, we

Human activities generate many different forms of pollution that are harmful to our environment, for example; water pollution. Pollutants change the pH balance of the water sources

The relatively close pH levels of Tap Water, Spring Water, Flavored Water, and Seltzer Water. Introduction This experiment was performed to investigate the following hypothesis: The following four different types of drinking water (spring water, seltzer water, tap water, and flavored water) we test will relatively have the same pH level. Our group decided to test different types of drinking water to see if a pH level of tap water is comparable to other types of water. Many people believe

The goal of the project was to characterize an "unknown" organic acid in order to make a proper identification of the acid, while learning proper techniques for scientific measurement and analysis of error. In order to ensure the most accurate data, a purification was performed by the process of recrystallization. To perform the recrystallization the powder was dissolved in a minimal amount of hot ethanol/H2O solvent that allowed the unknown powder to crystallize properly when cooled. This process

occurs in the absence of oxygen molecules also known as an anabolic reaction. It is a process of glycolysis in which sugar molecules are used to create ATP. Fermentation has many forms the two most known examples are lactic acid and alcoholic fermentation (Cressy). Lactic acid fermentation is used in many ranges from food production such as bacteria to its use by fatigued muscles in complex organisms (Cressy). When experimenting with organisms such as yeast which was done in this experiment you follow

experiment is to successfully perform a dehydration of 1-butanol and 2-butanol, also dehydrobromination of 1-bromobutane and 2-bromobutane to form the alkene products 1-butene, trans-2-butene, and cis-2-butene. The dehydration reactions react under and acid-catalysis which follows an E1 mechanism. It was found that dehydration of 1-butanol yielded 3.84% cis-2-butene, 81.83% trans-2-butene, and 14.33% 1-butene, while 2-butanol is unknown due to mechanical issues with the GC machine. For the dehydrobromination

Lab 1: Acid/Base Properties of an Antimicrobial Agent 09/03/13 Purpose The purpose was to determine the acid and base properties of the antimicrobial agent sodium benzoate. Theory Sodium has mainly been used in food processing to avoid growth of bacteria and harmful microorganisms. It is commonly used to preserve foods and beverages that have an acidic pH. Rather than benzoic acid, sodium benzoate is used because it is generally soluble in most aqueous solutions but benzoic acid is not
