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 reactants is equal to the number of products. The number of reactants is equal to the number of products. 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 atoms of each element is the same on both sides.

Answer 1

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

This demonstrates the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. In the given balanced equation (4Fe + 3O2 → 2Fe2O3), there are an equal number of each type of atom (Fe and O) on both the reactant and product sides of the equation.
