Question

Describe the characteristics of compound and mixture using Sulphur and iron fillings.​

Answer 1

Explanation:

When iron filings and sulphur powder are mixed, both retain their properties. It means they have not undergone any chemical reaction. Therefore, mixing of iron and sulphur is a physical change. When iron filings and sulphur powder are mixed and heated they undergo a chemical reaction and form ferrous sulphide (FeS).
