WebPyrrhotite, which is chemically called iron sulfide, has the ideal formula FeS (Fe = iron, S = sulfur). This formula means that in ANY AMOUNT of pyrrhotite, the ratio of iron to sulfur will be 1:1. The equation for the reaction that produces the iron sulfide is: Fe + S FeS (heat) Maine Geological Survey 2 WebThis demonstration or class experiment shows the exothermic reaction of iron and sulphur.
