Pyrite is made of iron and sulfur and is the compound iron sulfide with the chemical formula FeS2. It is not a mixture of iron and sulfur. The iron and sulfur are chemically combined to form a compound.
Well, if we mix iron sulfur mixture and hydrochlonic acid, only the iron reacts.
A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.
No, it is a mixture, as they are not liquids.
Yes, a magnet is one way that can be used to separate a mixture of iron filings and sulfur.
It's just physical, unless you heat the mixture. The simple combination of iron and sulfur is a physical mixture: It can be separated with a magnet, and the iron and sulfur are still themselves. The situation changes if you heat the mixture hot enough to start a reaction between the sulfur and iron. If you do so, assuming the ingredients are in the right proportions, you'll have iron sulfide (a compound) and no free iron or sulfur will remain. In that case, you have a chemical reaction.
Sulfur and iron filings together are a mixture.
No, the mixture of powdered sulfur and iron filling are not a homogenous mixture, they are a heterogenous mixture.
Reacting iron with sulfur an iron sulfide is formed, not a mixture.
Well, if we mix iron sulfur mixture and hydrochlonic acid, only the iron reacts.
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.

Iron sulfide, FeS2, makes up the crystalline mineral pyrite, also known as fool's gold.
