2 C6H14+ 190 2 ~ 12CO2 +14H2O
This equation shows 38 atoms of oxygen on the reactant side how many atoms of oxen on the product side
On the product side, there are 12 CO2 molecules. Each CO2 molecule contains 2 oxygen atoms.
Therefore, the total number of oxygen atoms on the product side is:
12 CO2 * 2 oxygen atoms = 24 oxygen atoms.
