Chemical Aspects of Life and Spit Lab Formal Report 1. Abstract The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective

They then examined these samples through the SEM‚ XRD‚ and TGA to learn more about the properties and differences. The SnSp (powdered) species came from the SnSg (granular) synthesis during solvent exchange and the CO2 supercritical drying process. They found that the PAN hybrid was very much more mechanically stable than pure chalcogel‚ even though the as-made chalcogels adsorbed iodine more quickly‚ and more effectively. The

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Environmental Working Group’s analysis suggests that 97 percent of hair relaxers‚ 57 percent of baby soaps and 22 percent of all products in Skin Deep may be contaminated with 1‚4-dioxane [1]. Independent lab tests co-released by the Campaign for Safe Cosmetics in 2007 showed that popular brands of children’s bubble bath and body wash contained 1‚ 4-dioxane HEALTH CONCERNS:

Synthesis of Aspirin and Oil of Wintergreen INTRODUCTION: Synthesis and use of organic compounds is an extremely important area of modern chemistry. Approximately half of all chemists work with organic chemicals. In everyday life‚ many if not most of the chemicals you come in contact with are organic chemicals. Examples include drugs‚ synthetic fabrics‚ paints‚ plastics‚ etc. Synthesis of Aspirin and Methyl Salicylate. The two compounds we will be preparing‚ aspirin (acetylsalicylic acid) and oil

According to Figure 4 and 5‚ the moles of Cu initially obtained and at completion‚ differentiated. It was evident that the initial moles of Cu (0.0254)‚ did not regenerate all the amount‚ as 0.0124 moles of Cu was attained. In regards to this‚ the no. moles that was eliminated was approximately‚ 0.013. Respectively‚ in Figure 3‚ a large deviation amongst the initial and final quantity of copper‚ this implies that the rest of the mass that had diminished‚ was greater than the final product. These

making the bacteria take on various phenotypic characteristics. Background Information: Genetic transformation is one of the most important processes in biotechnology. Essentially‚ genetic transformation involves the process where a cell (in this lab‚ a bacterial cell) takes up foreign DNA from its surroundings and incorporates it into its own DNA. This gene transfer is accomplished with the aid of a plasmid‚ a

Abstract This experiment investigated the kinetics of the enzyme glycogen phosphorylase b which is important to metabolism. AMP is an allosteric activator of the enzyme because it converts glycogen phosphorylase b from its T state to the R state which is the active form. Caffeine is an inhibitor because it binds the nucleoside inhibitor site. When it binds this site‚ it stabilizes the inactive T state and blocks the catalytic site which needs to be open for enzyme activity to occur. The glycogen
