The sum of the coefficients and subscripts is the same on both sides.
The number of atoms of each element is the same on both sides.
Each element has the same subscript or coefficient on each side.
The number of reactants is equal to the number of products.

The correct response is:
The number of atoms of each element is the same on both sides.
This reflects the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. In the given equation, the number of iron (Fe) atoms and the number of oxygen (O2) molecules are balanced on both sides, confirming that the total mass remains constant.
