A) What does the Law of Conservation of Mass say about a chemical reaction? (1 point)
In a chemical reaction, mass is neither created nor destroyed.
To balance a chemical equation, additional mass may be created.
Mass increases as atoms are rearranged during a chemical reaction.
Mass is not measurable in a chemical reaction.
