Hello, and thank you for posting your question to BrainMass.
Let's write the equation with arbitrary coefficients:
a FeS2 +b O2 ---> c Fe2O3 + d SO2
Now we equate the number of atoms of each specie on both sides:
Fe: a = ...
This response provides assistance in balancing an equation and explains whether or not the reaction is combustion.
