Chemical compound and physical mixture. Iron sulphide (FeS, left) is a chemical compound composed of iron and sulphur. They can not be separated without destroying the compound. Iron sulphide is not magnetic and is not attracted to the ALNICO magnet here. In the iron and sulphur mixture (Fe and S, right) constituents are not chemically bonded to each and retain their individual properties. Since iron is magnetic and sulphur is not, they can be physically separated with a magnet. | |
