An Easy Quiz On Stoichiometry
Stoichiometry is the calculation that deals with the amount of reactants required and the amount of products formed during a chemical reaction. It is based on the Law of Conservation of Mass according to which the total mass before and after a chemical reaction remains undisturbed. The following quiz is an easy stoichiometry test. Balance all equations before solving. Good Luck!
