Solution 1) Changes to be made to the data equations a) reverse equation 1 (this puts Fe 3 O 4 on opposite side to compensate for switching equation 3) b) multiply equation 2 by 3 (this will give 3Fe 2 O 3 allowing it to cancel) c) reverse equation 3 and multiply it by two (this puts FeO on the reactant side and gives us 2Fe 3 O 4 to cancel) Please note that no attention was paid to CO

Chemical Equations (previous version)

In writing chemical equations the number in front of the molecule's symbol (called a coefficient) indicates the number of molecules participating in the reaction If no coefficient appears in front of a molecule we interpret this as meaning one In order to write a correct chemical equation we must balance all of the atoms on the left side of the reaction with the atoms on the right side
