Iron sulfide, FeS2, makes up the crystalline mineral pyrite, also known as fool's gold.
Iron sulfide
Sulfur and iron filings together are a mixture.
Heating sulfur with iron fillings lead to the formation of iron sulfide - a chemical compound.
iron sulphide
1. Iron is lustrous, while sulfur is not. Luster is a property of metals. 2. Iron conducts electricity, while sulfur does not. Electrical conductivity is a property of metals. 3. Iron conducts heat, while sulfur does not. Heat conductivity is a property of metals. 4. Iron is malleable, while sulfur is not. Malleability is a property of metals. 5. Iron is somewhat ductile, while sulfur is not. Ductility is a property of metals.
Iron sulfide is brown crystals. Iron is a silvery metal. Sulfur is bright yellow crystals. Sulfur burns with a bright flame. Iron doesn't burn and iron sulfide doesn't burn well.
The residue obtained from heating crystals of FeSO4 (iron(II) sulfate) is Fe2O3 (iron(III) oxide) and SO2 (sulfur dioxide) gases. This is because the heating process causes the iron(II) sulfate to decompose, releasing water vapor, sulfur dioxide gas, and leaving iron(III) oxide as a solid residue.
Iron is a metal but sulfur is a nonmetal.
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.
Iron sulfates contain iron, sulfur and oxygen.
Iron is silver while sulfur is yellow, Iron is magnetic while sulfur is not, and Iron looks like dirt and sulfur looks like yellow powdered sugar
iron sulfide
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.
Iron sulfide
Use a magnet to extract the iron from the sulfur.
The iron and sulfur react to form the compound iron sulfide.
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.
