procedure is to use laboratory techniques to determine the mass of each element in the compound. In this lab‚ we will react a known quantity of magnesium metal to form chloride product. We then mass the final product and subtract to find the mass of chlorine in the product. Once we know the masses of elements in the compounds‚ we can convert to moles and determine the simplest whole number mole ratio. Objective The objective of this lab is to determine the empirical formula of magnesium chloride.

This article is about public and private swimming pools being contaminated with E. coli. Chlorine is not doing its job in sanitizing the human waste in the swimming pool. Human waste seems to refuse being sanitized. The Centers for Disease Control (CDC) concluded that the E. coli came from one major primary source; swimmers pooping in the swimming pool. Researchers say such contamination is due to swimmers not rinsing themselves off before going in the pool. Scientists say a person carries about

INORGANIC CHEMISTRY 1 Lab Report on Oxidation & Reduction I. Metal-Metal Ion Displacement II. Halogen Displacement Reactions INTRODUCTION A series of experiments had been conducted to determine the order of displacement strengths of the metals and halogen chosen for the experiments. A displacement reaction is a reaction in which one element(metal or non-metal) displaces another element(metal or non-metal) from its salt solution. In the displacement reaction of metals‚ the more

useful. These classes of compounds find wide applications in industry as well as in day-to-day life. They are used as solvents for relatively non-polar compounds and as starting materials for the synthesis of wide range of organic compounds. Chlorine containing antibiotic‚ chloramphenicol‚ produced by soil microorganisms is very effective for the treatment of typhoid fever. The compounds containing more than one halogen atoms are commonly called as polyhaloalkanes‚ or polyhaloarenes depending

There are two important things to do in a dental office in order to prevent cross infection. These two forms are sterilization and disinfection. According to the CDC and the Food and Drug Administration before either of these forms can be used you have to clean the instruments. This can be done either by hand or by using an ultrasonic cleaner. (http://www.maexamhelp.com/instru_sterilization.htm) Even though both sterilization and disinfection are both important there is a big difference between

t-Pentyl Chloride is a compound that is created through an SN1 nucleophilic substitution reaction in addition with Hydrogen Chloride in order to isolate the product. A variety of procedural techniques were utilized during the experiment including extraction‚ washing liquids‚ drying liquids‚ gravity filtration‚ and simple distillation. When a single solute or compound is transferred between two different solutes‚ it is known as extraction. Another technique that was utilized was washing‚ in which

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied

Introduction The purpose of this experiment is to determine if the amount of zinc and hydrochloric acid will effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric acid to produce a compound of zinc and chlorine atoms. We are then recording our data and observations and place it in a logical data table. Purpose The whole purpose of this experiment is to determine wether or not the amount of the zinc and or hydrochloric acid effects the out coming
