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.
The iron (II) sulfide (FeS) is obtained.
use a magnet for separating it the iron fillings will go to the magnet and the sulfer will stay on the ground :)
a magnet
Yes you can. You might do it with a magnet.
yes, just use a magnet
Heating sulfur with iron fillings lead to the formation of iron sulfide - a chemical compound.
iron sulfide
The iron and sulfur react to form the compound iron sulfide.
you use a magent
it is a heterogenous mixture
The iron (II) sulfide (FeS) is obtained.
use a magnet for separating it the iron fillings will go to the magnet and the sulfer will stay on the ground :)
If you put the magnet near the iron fillings, they will be drawn out by the magnetic pull of the magnet.
The iron fillings are attracted by the magnet and separated from the sulphur powder.
It is not a chemical change. The iron and sand can be separated out.
Using a magnet would be the easiest way.
