Name two elements that combine to make iron sulphide what are their chemical symbols

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).

the answer is learned

wher is the rest of the question
