Domoic acid

of matter. They thought that it was possible that individual particles made up matter. As you might imagine, it's useful to be able to measure the acidity of solutions. Scientists have come up with the pH scale for determining the concentration of acid in a solution so we can distinguish between solutions with varying acidity. A Chemical reaction is the outcome of two or more elements together results in the formation of a chemical bond between atoms and compound. Chemicals react together

Respiration is the process that takes place in every living cell to make energy available to the body. Energy is vital for us to carry out many life processes such as movement and so respiration in essential to life. During respiration glucose and oxygen are used in a reaction that produces energy and gives out carbon dioxide and water as waste products. Glucose is obtained by digestion of food and oxygen is taken from the air during a process called breathing or ventilation. Pulmonary Ventilation

carbonation will occur when water reacts with carbon dioxide to form a carbonic acid, which can hollow out rocks by breaking them down, leading to cave formations. Purpose: The purpose of this lab is to demonstrate the effects of chemical weathering on zinc. Hypothesis If metal is placed in mixture of acid and water then the amount of rust will increase because the metal will be more exposed to the acid for a period of time with one or the other mixture

Enzyme Lab Report Hydrogen peroxide is a toxic byproduct of cellular functions. To maintain hydrogen peroxide levels the catalase enzyme deconstructs hydrogen peroxide and reconstructs the reactants into oxygen gas and water. The catalase enzyme is found inside cells of most plants and animals. Regulating the levels of hydrogen peroxide is crucial in homeostasis and analyzing it’s optimal conditions for performance is just as important. To understand the optimal environment for this enzyme, they

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

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
