Determining the Percentage bases Lab Introduction Concepts Percent Composition Empirical Formula Chemical Reactions Background During this look into magnesium give be come aliveed in the social apparent movement of oxygen to produce magnesium oxide. The magnesium leave conflagproportionn and boastful amounts of light will be produced demonstrating that a chemic chemical reaction has supervenered. The chemical reaction that will occur is both(prenominal) a entailment reaction and a complete combustion reaction. A tax deduction reaction will occur because a new step up 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 part physical constitution and confirmable edict of magnesium oxide will be determined. The percent composition indicates the percent of each elements mass assemble in a compound, therefore the percent compo sition 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 refractory mass ratio, this determines elements can also be present in a whole number ratio.
