If iron pyrite, FeS2, is not removed from coal,
oxygen from the air will combine with both
the iron and the sulfur as coal burns. If a
furnace burns an amount of coal containing
100.0 g of FeS2, how much SO2 (moles), an air
pollutant, is produced? (Note, iron (III) oxide
is also one of the products.)
FeS2 + O2 ==> Fe2O3 + SO2
100.0 g FeS2 * 1 mole FeS2 * 8 mole SO2
