Question

What happens when iron fillings are heated with sulphur powder? Is the change physical or chemical? Justify your answer. ​

Answer 1

Answer:

When iron filings and sulphur powder are mixed and heated they undergo a chemical reaction and form ferrous sulphide (FeS). It is a new substance which has properties entirely different from Fe and S. Therefore, heating of a mixture of iron and sulphur powder is a chemical change.
