Step 5 Balance the hydrogen atoms next. You have 8 on the left side, so you'll need 8 on the right side. C3H8 + O2 --> 4H2O + 3CO2 On the right side, we added a 4 as the coefficient because the subscript showed that we already had 2 hydrogen atoms. When you multiply the coefficient 4 times the subscript 2, you end up with 8. Step 6 Finish by balancing the oxygen atoms. Because we've added coefficients to the molecules on the right side of the equation, the number of oxygen atoms has changed. We now have 4 oxygen atoms in the water molecule and 6 oxygen atoms in the carbon dioxide molecule. That makes a total of 10 oxygen atoms. Add a coefficient of 5 to the oxygen molecule on the left side of the equation. You now have 10 oxygen molecules on each side. C3H8 + 5O2 --> 4H2O + 3CO2. The carbon, hydrogen and oxygen atoms are balanced. Your equation is complete.
