Melendez January 31, 2017 BSC2010 Enzyme I: pH and Temperature Lab Report Introduction: (2008, November 11). Without Enzyme, Biological Reaction Essential To Life Takes 2.3 Billion Years. Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s makeup…

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 towels and trash bags at the ready. Demo and discussion: To introduce the idea of physical versus chemical…

rate of reactions are affected by volume affects and determine which chemical affects the solution rate of reaction. Temperature was also a factor in discovering how it will affect the speed of the reaction. This was done by gathering certain chemicals and mixing them into a test tube then recording how long it took to change color. Temperature was tested by placing the test tube in ice water over a hot plate and slowlying increasing the temperature. Sodium thiosulfate slows the rate of reaction…

through the process of a chemical change.it is important to understand their chemical properties in order to put it in the correct container that is appropiate. This means that the temperature, pressure, and concentration must remain consistent throughout time. However, a chemical change is sometimes required in order to understand the substance better. For example, some chemicals may need to be introduced to fingerprints which may not be visible to the eye. When chemicals are added to it, it…

CHANGES IN CHEMICAL REACTIONS INTRODUCTION This practical experiment is based is based on the theory of Law of Conservation of Mass stated by Antoine Lavoisier. Antoine Lavoisier was a French nobleman who had a major influence on the history of chemistry and biology. Today he is considered to be the “father of modern chemistry.” In all his experiment he supported the Law of Conservation of Mass. Antoine stated this in his theory, “The law of conservation of mass states that mass can neither be…

that measures the quantity of chemicals in a reaction. This branch relies heavily on moles and balancing. A mole is a unit of measure for giant quantities. It is a number of atoms or molecules that is so large that it is only logical and convenient to use it for atoms and molecules. One mole is 6.02 x 1023 atoms or molecules. We call this Avogadro's Number. Furthermore, balancing chemical equations is the process of changing determining the coefficients in a chemical equation, making sure that…

conducted involved a process called the Maillard Reaction. When it comes to cooking meats, heating the food causes the proteins, especially those nearest the surface of the meat, to denature. These denatured proteins become more chemically reactive to other molecules in their environment. One of the primary reactions that occur when browning meats and many other foods is called the Maillard Reaction. The Maillard Reaction is a non-enzymatic chemical reaction between amino acids and reducing…

The formation of benzilic acid results from the reaction of benzil with ethanol and potassium benzilate. In order to produce benzil, benzoin was reacted with nitric acid. A crude product of benzil was produced from the reaction of benzoin and nitric acid. Through the process of multi-step synthesis, benzil was produced through the oxidation of an alpha-hydroxyketone to an alpha-diketone using nitric acid. Prior to the reaction of nitric acid and benzoin, nitric acid was protonated to form an…

Introduction The reaction of Hydro Chloric Acid with Aluminum is exothermic and very dynamic. The Hydrogen produced at such temperatures can easily explode by combining with the oxygen of the atmosphere. This reaction is known as a single displacement reaction because aluminum switches with the hydrogen. When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al + 6HCl =…

This demonstration is called Elephant’s Toothpaste because the chemical reaction produces a large foamy mess that looks like toothpaste squirting out of a tube. We want to do this project because we want to show how this science experiment works and tell the reactions of it. How It Works: This large demonstration uses hydrogen peroxide, sodium iodide and soap. First, we pour in the hydrogen peroxide, then the soap and finally the sodium iodide. The yeast contains an enzyme called Catalase…
