The theory of conservation of mass, first formulated by Antoine Lavoisier in the 18th century, is supported by numerous experiments demonstrating that mass remains constant in closed systems during chemical reactions. For instance, when reactants are combined in a sealed container, the total mass before and after the reaction remains unchanged, regardless of the nature of the products formed. Additionally, the principle is validated in various physical processes, such as combustion and synthesis, where all atoms present before the reaction are accounted for in the products. This consistency across diverse scientific observations reinforces the validity of the conservation of mass in both chemistry and physics.
