According to the law of conservation of mass, in a chemical reaction, matter is not created or destroyed and the same amount of mass remains. This means that the total mass of the reactants must equal the total mass of the products, even though the substances may change form and appearance during the reaction.
Keesha performed a chemical reaction and the products looked quite different from the reactants. She knew the amount of matter had not changed due to the law of conservation of mass. According to the law of conservation of mass, what happens in a chemical reaction?
