What does the Law of Conservation of Mass state?

Explanation:
Matter is not created or destroyed in a chemical reaction. The total amount of matter stays the same because the atoms you start with are the atoms you end up with, just rearranged into different substances. In a closed system, the mass of the reactants equals the mass of the products, even though the substances might look different after the reaction. Energy can be released or absorbed, but that doesn’t change the total mass. So the idea that mass is neither created nor destroyed best captures what happens during chemical changes.
