Question

What happens when a mixture of iron and sulphur are heated? give the equation involved?
​

Answer 1

Answer:

Iron and sulfur react together when they are heated to make a compound called iron sulfide. ... the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide

Answer 2

Explanation:

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. Solid and molten sulfur can be ignited; burning sulfur produces sulphur dioxide, an irritating, toxic, and suffocating gas. t shows the exothermic reaction of two elements, iron and sulfur, to form the compound, iron sulfide.

The equation for the reaction that produces the iron sulfide is: Fe + S → FeS (heat)
