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. 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. Each element has the same subscript or coefficient on each side. Each element has the same subscript or coefficient on each side. The number of atoms of each element is the same on both sides.

1 answer

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

This shows the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction. In the balanced equation \(4Fe + 3O_2 → 2Fe_2O_3\), the number of atoms of each element (iron and oxygen) is the same on both sides of the equation, indicating that the total mass remains constant throughout the reaction.
