Question

4 FeS2 (s) + 11 O2 (g) = 2 Fe2O3 (s) + 8SO2 (g) a) Calculate the number of moles of FeS2 which would be required to react with 9.32 moles of Os in the reaction ( mol FeS2) b) Calculate the number of moles of SO2 which would be produced by the reaction of 9.54 moles of O2 with an excess of FeS2 ( mol SO2) c) Calculate the number of moles of Fe2O3 which would be produced by the reaction of 6.56 moles of O2 with and excess of FeS2 ( mol Fe2O3)
