According to the law of conservation of mass, which quantity remains the same before and after a chemical reaction?

Answer and explanation

Correct answer: Total mass

According to the law of conservation of mass, mass is neither created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants equals the total mass of the products. Temperature and volume may change, and the physical state of substances may also change.
