The correct response is:
The number of atoms of each element is the same on both sides.
This response clearly indicates that the same number of atoms for each element (iron and oxygen in this case) is present in the reactants and products, thereby demonstrating the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
