Detailed explanation-1: -The law of conservation of mass states that the net change in mass of the reactants and products before and after a chemical reaction is zero. This means mass can neither be created nor destroyed in other words, the total mass in a chemical reaction remains constant.

Detailed explanation-2: -Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change-none is created or destroyed. This concept is called the Law of Conservation of Mass.

Detailed explanation-3: -The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed.

Detailed explanation-4: -The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.

Detailed explanation-5: -Assertion: In a chemical reaction, the sum of the masses of the reactants and products remain unchanged. Reason: According to the law of conservation of mass, mass can neither be created nor destroyed.
