1 Look at the following chemical equation. 4FeS + 702 → 2Fe2O3 + 4SO2 What is true about this chemical equation? A. It is balanced because the mass of the reactants is equal to the mass of the products. B. It is unbalanced because the mass of the reactants is greater than the mass of the products. C. It is balanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products. D. It is unbalanced because the sum of the coefficients of the reactants is greater than the sum of the coefficients of the products,
