balanced reaction equation must have the same number of atoms of each element on both sides of the equation. The reaction   CH3COCH3+4O2→3CO2+3H2OCH3COCH3+4O2→3CO2+3H2O   represents the combustion of acetone. Count the atoms of each element on both sides of the reaction. How many of each atom are there on the reactants side?
