Complete the FeS + O2 reaction equation.

The reaction takes place between iron sulfide and oxygen. As a result of the reaction, trivalent iron oxide and tetravalent sulfur oxide are formed. The chemical equation for the reaction is as follows:

4 FeS + 7 O2 = 2 Fe2O3 + 4 SO2.

In order to bring the reaction into equilibrium, we need to put 4 in front of sulfur sulfide, put 7 in front of oxygen, put 2 in front of ferric oxide, and 4 in front of tetravalent sulfur oxide.
