How can a chemical equation be balanced? Responses by using exponents to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants by using exponents to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants by using new elements to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants by using new elements to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants by using subscripts to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants by using subscripts to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants by using coefficients to adjust the number of atoms of each element so that the products have the same number of atoms of the same element as in the reactants
