How is a chemical equation balanced?
How do you know which coefficients to add?
The coefficients are determined by using the lowest common multiple of the molecules in the equation. For example, if you have H2O on the left and O2 on the right, you would need to add a coefficient of 2 to H2O and 1 to O2 in order to balance the equation since you need two oxygen atoms on the left to match the two on the right.
