... Adding this coefficient balances H but gives four O atoms in the products. Because there are only three O atoms in the reactants, we are not finished. We can place the 3/2 coefficient in front of O2 to give four O Atoms in the reactants (3/2 x 2 = 3 O atoms in 3/2 O2) CH3OH(l) + 3/2O2(g) CO2(g) + ...
