Webthe balanced reaction will be 4FeS2+11O2 -> 2Fe2O3+8SO2. It is a redox reaction.Number of electrons gained =Number of electrons lost. 1 mole of FeS2 = (11/4) moles of O2. Each O atom takes 2 electrons for reduction. Therefore for 1 O2 molecule 4 electrons are absorbed for reduction. Therefore number of moles of electrons gained by O2 = (11/4)*4=11.
