REAC 714 Studying SN1 and SN2 Reactions: Nucleophilic Substitution at Saturated Carbon Date of Experiment: February 6‚ 2008 Objective: The objective of this laboratory experiment is to study both SN1 and SN2 reactions. The first part of the lab focuses on synthesizing 1-bromobutane from 1-butanol by using an SN2 mechanism. The obtained product will then be analyzed using infrared spectroscopy and refractive index. The second part of the lab concentrates on how different factors influence the rate

Organic Chemistry Project About Saturated and Unsaturated Fats in Vegetable Oils‚ Margarines‚ and Peanut Butters Submitted by : Zedrik O. Ortiz Submitted to : Dr. Luzviminda H. Saliga DEFINITION OF TERMS Saturated fat is a fatty acid that consists of triglycerides containing only saturated fatty acids. Saturated fatty acids have no double bonds between the individual carbon atoms of the fatty acid chain. That is‚ the chain of carbon atoms is fully saturated with hydrogen atoms. There are

An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

Anatomy and Physiology Assignment Research project: The role of calcium and vitamin D in the development and maintenance of bone structure What is Parathyrin? Parathyrin is a substance made by the parathyroid gland that helps the body store and use calcium. A higher than normal amount of parathyrin causes high levels of calcium in the blood and may be a sign of disease. Parathyrin is also sometimes known as Parathormone‚ parathyroid hormone and PTH. What is Calcatonin? Calcatonin is a hormone

mechanical restitution is driven by calcium movement and concentrations. An increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release from the sarcoplasmic reticulum via Calcium-Induced Calcium Release (CICR). Calcium binds to the ryanodine receptor on

Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by
