A Lab activity with a video pre-lab assessment - Josh Kenney; Activities. According to the law of the conservation of mass, in a chemical reaction, there must be the same number of atoms of each kind on both sides of the equation. To manipulate chemical reactions on a large scale, scientists use stoichiometry to quantify those reactions and make sure that there are just the right amount of reactants and products. Chemical reactions relate quantities of reactants and products. Since matter is conserved in a chemical reaction, chemical equations must balance for mass.
