The easiest way would be to use a magnet. Iron is naturally magnetic, and will respond to and follow a magnet, while sulfur is not magnetic and will stay in its place.

How could a student use a magnet to indicate that combining iron an sulfur to produce the mixture of iron and sulfur is a physical change?
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.
What can a mixture of iron and sulfur be separated by?
magnetic attraction
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.
Can Iron filings be separated from a mixture with sulfur by using a magnet?
Yes, a magnet is one way that can be used to separate a mixture of iron filings and sulfur.
A mixture of iron filings and sulfur can easily be separated by?
by using 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.
How do you know iron sulphide is not a 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 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.
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)
Hypothesis of separating iron filing and sulfur powder?
As the mixture of iron filings and sulphur powder are together/mixed it can be easily separated by a magnet.
Is unheated sulfur and iron filings is substance or mixture?
Sulfur and iron filings together are a mixture.
What is mixing sulfur with iron fillings?
When you mix Iron filings and Sulphur crystals together, you form a mixture of Iron and Sulphur from which both the components can be separated by physical means. But if you heat the mixture strongly, then it becomes a compound of Iron Sulphide from which the two components cannot be separated by physical means.
