Answer 1

It is a chemical change because :-

• When iron filings and sulphur powder are mixed and heated they undergo a chemical reaction and thus form ferrous sulphide (FeS) which is a new substance with properties entirely different from Fe and S.

Therefore, heating of mixture of iron and sulphur powder is a chemical change.
