13. The Law of Conservation of Mass states that matter cannot be created or destroyed
but transferred. This law was proven by the scientist Antoine Lavoisier, who heated
various substances and documented quantitative relationships. His observations proved
that the mass of the reactants is equal to the mass of the product in a chemical reaction.
Justify (give good reason) why Lavoisier's conclusions were considered a law instead of a
theory,

A. Lavoisier attempted to explain the results of his experiments.
B. Lavoisier provided sufficient empirical evidence to support his claim..
Lavoisier provided an explanation of an observed phenomena in nature.
D. Lavoisier applied the results of one experiment to explain a wide variety of
circumstances.
