Determining the Percentage compositions Lab Introduction Concepts Percent Composition Empirical Formula Chemical Reactions Background During this look into magnesium give be come aliveed in the social execution of oxygen to produce magnesium oxide. The magnesium exit conflagproportionn and commodious amounts of light will be produced demonstrating that a chemic response has go alongred. The chemical reaction that will occur is both(prenominal) a entailment reaction and a complete combustion reaction. A entailment reaction will occur because a new heighten will be formed by two elements that reacted. A complete combustion also will also occur because energy in the form of heat and light will be produced. The pct physical constitution and confirmable legislation of magnesium oxide will be determined. The percent composition indicates the percent of each elements mass assemble in a compound, therefore the percent composition describes the composition of a substance. The empirical formula demonstrates the smallest whole number ratio of the elements in a compound. If elements are prove in a dogged mass ratio, this determines elements can also be present in a whole number ratio.
