A new substance is formed with different properties from iron and sulphur.
Iron and sulphur make iron sulphide
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.
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.
No Iron sulphide is a compound
The way you phrase that is a little dubious because no mixture is a 'pure substance'. However, compounds like iron sulphide that are actually bonded together areconsidered pure substances. The elements of a mixture are not united by a chemical change and can (in theory) be separated.
Iron sulfide is a compound.
unknown
well, iron sulphide is a compound so tin sulphide proberly is.
Iron sulphides are chemical compounds.
It is a compound because iron and sulfur are two individual elements that you can find on the periodic table.
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.
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.
Yes, the reaction is possible when the mixture is heated.
It is a chemical reaction
A mixture of Iron and Sulphur is exactly that, iron filings mixed with sulphur that has not undergone any chemical reaction. Iron sulphide is the result of the reaction of Iron with sulphur.
Iron and sulphur make iron sulphide
If it is a simple mixture of Fe and S you can use a magnet to separate iron. Of course, the method is not valid for an iron sulphide.
