How do I balance my equation?
o balance an equation, you will need to make sure that the same number of atoms are on each side. This can be done by adding coefficients (numbers placed in front of elements) until the numbers match up. For example:
2Fe + O₂ → 2FeO
In this case, we need to add a coefficient of “2” in front of the oxygen molecule on the left-hand side so that there are two oxygens on both sides:
2Fe + 2O₂ → 2FeO
