Determining the Percentage make-ups Lab Introduction Concepts Percent Composition Empirical Formula Chemical Reactions Background During this look into milligram give be come aliveed in the social action of oxygen to produce magnesium oxide. The magnesium depart conflagproportionn and cock-a-hoop amounts of light will be produced demonstrating that a chemic reception has sinkred. The chemical reaction that will occur is both(prenominal) a subtraction reaction and a complete combustion reaction. A deductive reasoning reaction will occur because a new conflate 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 share physical constitution and confirmable expression of magnesium oxide will be determined. The percent composition indicates the percent of each elements mass assemble in a compound, therefore the percent composi tion 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 situated mass ratio, this determines elements can also be present in a whole number ratio.
