more. If you mean for the very last equation, there are 14 oxygens atoms on both sides. The reactant side has 7O2 which is 14 oxygen atoms (7x2=14). The product side has 4CO2 which is 8 oxygen atoms (4x2=8) and 6H2O which is 6 oxygen atoms for a total of 14 oxygen atoms (8+6 =14). Hope that helps. RxMyFj1.
