Wnich of the following statements about chemical equations is (are) /true? 1type='a'> When balancing a chemical equation, you can never change the coefficient in front of any chemical formula. i>The coefficients in a balanced chemical equation refer to the number of grains of reactants and products. i>In a chemical equation, the reactants are on the right, and the products are on the left. i>Wnen balancing a chemical equation, you can never change the subscripts of any chemical formula. i>In chemical reactions, the matter is neither created nor destroyed, so a chemical equation must have the same number of atoms on both sides of the equation.
