Answer 1

The correct response is:

The atomic mass of the reactants equals the atomic mass of the product, and the product has the same number of atoms as the reactants.

This illustrates the conservation of mass because during the chemical reaction in which hydrogen and oxygen combine to form water, the total mass of the reactants (hydrogen and oxygen) is equal to the total mass of the product (water). Additionally, the number of atoms of each element is conserved in the reaction, meaning that the total number of hydrogen and oxygen atoms before the reaction matches the total after the reaction.
