Forming Iron Sulfide

The video explores the properties of iron and sulphur, both individually and when combined. Initially, iron and sulphur are mixed physically, retaining their individual properties. A magnet test shows that only iron is magnetic. When heated, a chemical reaction occurs, forming iron sulphide, a compound with different properties. The experiment demonstrates that while physical mixing does not alter properties, chemical bonding does, as seen in the non-magnetic nature of iron sulphide despite containing iron.
