When an iron-sulfur mixture is heated, a chemical reaction occurs, resulting in the formation of iron sulfide (FeS). This new substance is a compound made up of iron and sulfur atoms bonded together. The reaction is exothermic, releasing heat and producing a black, brittle solid that has different properties than the original iron and sulfur.
