Question

What do you observe when a mixture of iron fillings and sulphur powder is heated strongly

Answer 1

if we heat a mixture of iron fillings and sulphur a compound is formed called iron sulphide. If a mixture of iron filings and sulphur is heated strongly then a greyish-Black substance called iron sulphide is formed.

Answer 2

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
