The first days in the lab will be used to practice with collecting bare footprints from different individuals using the bare footprint reagent cream. To get access to the lab‚ a Practical Risk Assessment must be made (see appendix I)‚ and three Health & Safety courses must be completed (see appendix II). After practicing with collecting bare footprints‚ the study starts with collecting footprints from six specific participants‚ whose footprints have already been collected by two other investigators

The Monsters of Christianity At first glance‚ the Epic of Beowulf and The Rule of St. Benedict appear to have little in common. In the tale of Beowulf‚ a hero seeks to fulfill his destiny by slaying multiple beasts and protecting the Danes until his fated death. On the other hand‚ The Rule of St. Benedict discusses how monks should live in a God centered community with one another. Despite their differences‚ both these medieval works are fighting vicious fiends‚ literally and figuratively‚ with

Purpose=The purpose of this lab was to combine reactants‚ which we would pick ourself‚ to make 2 grams of Copper Phosphate and another product. Background: Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Chemistry has to do with many things we use today. For example‚ fireworks are made by the chemical combining magnesium‚ titanium‚ copper‚ aluminum‚ strontium‚ or other periodical elements. Things also like making plastic‚ jewelry

Abstract: A qualitative analysis experiment was conducted to determine the identity of an unknown aldehyde or ketone. The tests include a Tollens test‚ a Schiff test‚ an iodoform test‚ and a derivative melting point test. The data of the first three tests was inconclusive. The final derivative melting point test was utilized to successfully determine that the unknown was the ketone‚ Propiophenone. Introduction: Qualitative analysis is a method or series of methods used to determine the

A. Objectives and background In an experiment‚ limiting reactant affect the “amount of the product.” In the other way‚ the product this reaction produce dependent on the limiting reactant. For example‚ 1000kg O2 and 1 gram H2 to form water. In this case‚ the 1 gram of H2 will be the limiting reactant. Same thing in displacement reactant. If one of the reactants is (Mole) less than the other one‚ then that reactants becomes the limiting reactants. Once the limiting reactants will completely be ran

Benedict’s Iodine‚ and Sudan III/IV. The Benedict’s test identifies reducing sugars (monosaccharide’s and some disaccharides)‚ which have free ketone or aldehyde functional groups). The groups reduce CuSO4‚ a component of Benedicts‚ resulting in a color change in the benedicts solution from a turquoise to a brick to rusty-brown color. Another class of carbohydrates called starches‚ a polysaccharide‚ can be detected using the Iodine’s test. Having a high molecular weight‚ iodine attaches to the helical
