This reaction between iron and sulphur forms iron sulphide, a compound with distinct properties from its constituent elements. The process involves heating a mixture of iron filings and sulphur powder, resulting in a chemical change that cannot be easily reversed.
- Iron sulphide (FeS) is created through an exothermic reaction between iron and sulphur.
- The reaction requires heat to initiate, causing sulphur to melt and bond with iron.
- Unlike a simple mixture, iron sulphide cannot be separated using a magnet due to its chemical bonds.
- The iron and sulphur reaction equation is Fe + S = FeS, representing a 1:1 ratio of atoms.
- This process demonstrates the difference between physical mixtures and chemical compounds.
