The result of heating iron filings and sulfur powder mixture shows an exothermic reaction which forms a compound, iron sulfide.
black
Please see the page for iron(II) sulfide on wikipedia for details.
When iron sulfur mixture is heated, they react with each other. Then a black colored substance is formed. This substance is FeS (iron(ii) sulfide)
A mixture of iron filings and sulphur powder. If you want them to react you have to heat the iron to its melting point before you add sulphur.
FeS2 or Fe2S3
Iron sulphide, FeS
The hot iron particles oxidize in the presence of the sulfur particles to iron sulfide.
