6 CO2 + 6 H2O -> C6H12O6 + 6 O2
Work Step by Step
First, balance carbon with a coefficient of 6 on the left side of the equation. Then balance hydrogen with a coefficient of 6 on the left side of the equation. Now balance oxygen. Since carbon and hydrogen are already balanced, we then focus our attention to the oxygen molecule on the right side of the equation. Inserting a coefficient of 6 for this molecule will give a total of 18 oxygen atoms on both sides of the equation. The chemical equation is now balanced.
