Antoine Lavoisier made chemicals react within a closed container. The mass of the container and chemicals after the reaction weighed the same as the container and chemicals before the reaction showing that no mass was lost. This led to the Law of . Action-Reaction

Conservation of Mass

Explanation:

Lavoisier conducted many experiments of this type. He found in all cases that the mass of the reactants is equal to the mass of the products. His conclusion, called the states that in a chemical reaction, atoms are neither created nor destroyed. - www.classzone.com
