Question

the lower conservation of mass states that the mass of reactant must be equal to the mass of the product

Answer 1

Answer:

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants
