Laboratory Science Abstract 85% of all medical decisions are based on the results of clinical laboratory testing. Medical laboratory science is the use of clinical laboratory tests to detect‚ diagnose‚ monitor and treat disease. Blood‚ tissue and body fluid can be chemically analyzed and examined for foreign organisms and abnormalities. This information is then used by the medical team to make decisions regarding medical care. Laboratory scientists have made important contributions to the development

Separation of a Mixture of Solids PURPOSE: The purpose of this lab is to familiarize ourselves with the techniques associated with separating a mixture of different solids. We will learn how the unique properties of substances can aid in this process and help us distinguish each pure substance from one another.

of the Upper Nepean Catchment. The following is a summary of factors that affect water quality. Water may contain several ions‚ namely anions and cations which are toxic to humans. Hardness is the scum on water surface from significant concentrations of calcium and magnesium ions. Total dissolved solids is the measure of dissolved solids that are ionic in water. Turbidity is the presence of suspended solids in water which reduces penetration of light‚ resulting in a decrease concentration of

CHE 242 Tutorial 3: Problems & Answers Week 4: Feb 2- 6‚ 2009 1. Consider a gas that occupies 1.00 dm3 at a pressure of 2.00 bar. If the gas is compressed isothermally at constant external pressure‚ Pext‚ so that the final volume is 0.500 dm3‚ what is the smallest value Pext can have? Calculate the work involved using this value of Pext. Solution For compression to occur‚ the value of Pext must be at least as large as the final pressure of the gas. P1 = 2.00 bar‚ V1 = 1.00 dm3‚ V2 = 0.500

Baking Project There are several chemical reactions taking place in the general baking of cakes. Every ingredient has its own function and causes a different reaction Synthesis: * Egg yolks (modify molecule’s structure) helps the oil-based and water-based components of the cake mix together. When eggs are cooked‚ the protein molecules become uncurled when exposed to heat and create new molecular bonds with other nearby protein molecules. When the egg is completely cooked‚ it helps form a
