Answer 1

Answer:

Iron Sulphide is formed .

Explanation:

The equation for the reaction that produces the iron sulfide is: Fe + S → FeS (heat) Page 2 Maine Geological Survey | 2 One atom of iron (or a million atoms of iron) and one atom of sulfur (or one million atoms of sulfur) react with heat to make one molecule of iron sulfide (or a million molecules of iron sulfide)

Hope it helps.

Answer 2

Answer:

On heating the reaction mixture, the sulfur melts and reacts with the iron exothermically to form iron(II) sulfide.
