Why does a magnet pick up iron in a mixture of iron and sulfur but not in a compound of iron sulfide?

Iron's magnetic properties are due to the configuration of its electrons when it is in its elemental form. In iron sulfide iron is in the form of positive ions rather than neutral atoms. This changes the electron configuration and thus how iron will respond to a magnetic field.

Does iron and sulfur react when they are heated?
Iron is a magnetic substance, which means it is attracted by a magnet. On the other hand, Sulfur is a non-magnetic substance. If you place a magnet near a mixture of Iron and Sulfur, the iron pieces will stick to the magnet, while the sulfur powder will remain.
What mineral is made by sulfur and iron and is also a mixture?
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.
Is sulfur and iron an element or a compound or a mixture?
sulfur and iron are elements, sulfur a yellow powder and iron a metal. When mixed together at room temperature they do not react readily and constitute a mixture which can be separated say by using a magnet to attract the iron. Heat them up and a vigorous reaction ensues forming a chemical compound, black iron sulfide, Fe2S3 see link for experimental details
Is copper sulphate a mixture or an element?
It is a compound. ---------------------------- Copper sulphate is a compound (a salt) made up of the elements Copper and Sulfur and Oxygen (CuSO4).
How do you split iron sulfide into iron and sulfur?
get a magnet

How is iron sulphide a compound and not just a mixture of iron and sulfur?
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.
Describe why iron filings and sulfur can be classified as element compound or mixture?
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.

Is sulfide a mixture a compound or element?
Sulfur is an element. Sulfide, the ion formed by sulfur cannot exist on its own as a substance because it carries a negative charge and must be accompanied by a positive ion.
Is copper sulphate a mixture or an element?
It is a compound. ---------------------------- Copper sulphate is a compound (a salt) made up of the elements Copper and Sulfur and Oxygen (CuSO4).
How do you split iron sulfide into iron and sulfur?
get a magnet
Is hydrogen sulfide a compound?
Yes, it is a compound of hydrogen and sulfur, or sulfur dioxide.
What distinguishes a compound like copper sulfide from an ordinary mixture of copper powder and sulfur?
Copper Sulfide is a wholly different chemical from copper and sulfur, and thus shows different characteristics and is not dividable by physical means, while a mixture of copper and sulfur powder is just a physical mix.
Describe how to separate a mixture of iron and sulfur?
Iron powder is attracted by a magnet (so it can be 'drawn' away),Sulfur is dissolved in carbon disulfide (so it can be filtered through, leaving iron behind),But be careful: it is explosive, toxic and stinks (rotten cauliflower)
Is mixing iron filing and sulfur is a physical change?
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.
