Question

differentiate between what happens when you strongly heating a mixture of iron and sulphur powder​

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 mixture of iron and sulphur powder is a chemical change.

Answer 2

Answer :

When a mixture of iron fillings and sulphur powder is heated strongly the iron sulphide is produced.

• The melting point of the sulphur is less than the iron.
• That's why when we heat up the mixture of iron fillings and sulphur powder,the sulphur gets melted first.
• This melted sulphur reacts with the iron fillings present in the mixture and forms black coloured iron sulfide chemical compound.

Chemical equation :

Fe + S = FeS
