Question

The balanced chemical equation shows a reaction between iron (Fe) and oxygen ( O2 ). 4Fe+3O2→2Fe2O3 How does the equation show the law of conservation of mass? (1 point) Responses The number of atoms of each element 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. Each element has the same subscript or coefficient on each side. The sum of the coefficients and subscripts is the same on both sides. The sum of the coefficients and subscripts is the same on both sides. The number of reactants is equal to the number of products.

Answer 1

The correct response is: **The number of atoms of each element is the same on both sides.**

This clearly demonstrates the law of conservation of mass, which states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products. In this balanced equation, there are 4 iron (Fe) atoms and 6 oxygen (O) atoms on both sides, confirming that mass is conserved.
