The law of chemistry that states that matter cannot be created or destroyed is called the Law of Conservation of Mass. This principle was formulated by Antoine Lavoisier in the late 18th century and is one of the fundamental principles of chemistry. It states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. In other words, the total mass before and after a chemical reaction remains constant. This law is based on the understanding that atoms are neither created nor destroyed during a chemical reaction, but are rearranged to form different substances.
