Question

A law that states, "matter cannot be created or destroyed in a chemical reaction."

Answer 1

This law is known as the Law of Conservation of Mass, which states that the total mass of the reactants in a chemical reaction must equal the total mass of the products. This law was first proposed by Antoine Lavoisier in the late 18th century and is a fundamental principle of chemistry. It is based on the idea that atoms are neither created nor destroyed in a chemical reaction, but are simply rearranged to form new substances.
