Question

The reaction between Iron filings and Sulphur powder is an example of _______.

Answer 1

1. Iron sulphide is created when two elements—iron filings and sulfur—combine. It is a combined reaction and a chemical change.
2. When heated and combined, iron filings and sulphur powder create ferrous sulphide as a result of a chemical reaction ($\mathrm{FeS}$).
3. It is a brand-new chemical with wholly distinct features from Fe and S.
4. Thus, heating a powdered Iron and Sulphur combination causes a chemical change.
