Nothing at all. They mix together to form a mixture which can be easily separated using a magnet to pull the iron out of the Sulphur. However if the two are heated strongly then iron sulphide will form. Once this chemical reaction has occurred they are almost inseparably under normal conditions.
YELLOW
You get iron sulphide.
Iron will react, dissolving in acid and with hydrogen gas escaping from the surface. Sulfur stays unchanged.
Well, if we mix iron sulfur mixture and hydrochlonic acid, only the iron reacts.
All of the products of a reaction between pure iron and pure sulfur are solids at standard temperature and pressure. Doesn't matter if you're talking about iron(II) or iron (III), or at what stoichiometric ratio the sulfur bonds with the iron.
YELLOW
The iron and sulfur react to form the compound iron sulfide.
You get iron sulphide.

1 : 1
I want the answer
The iron (II) sulfide (FeS) is obtained.
The iron fillings are attracted by the magnet and separated from the sulphur powder.
