Explanation:

According to the law of conservation of mass, matter can neither be created nor destroyed, so the total quantity of matter, i.e., the total mass, before and after a change, remains the same. So, the mass of the substances, taken together, before and after a chemical change, will also remain same. From this, it can be concluded that any new substance formed during a chemical change is due to the rearrangement of the atoms of the original substance. The number of atoms of each kind remains the same, before and after the chemical change.
