Science. Explain why iron sulphide is a compound and not just a mixture of the two elements iron and sulphur. Explain why iron sulphide has different properties to a mixture of iron and sulphur and also describe and explain tests that can distinguish between iron sulphide and a mixture of iron and sulphur.
One atom of iron (or a million atoms of iron) and one atom of sulfur (or one million. atoms of sulfur) react with heat to make one molecule of iron sulfide (or a million. molecules of iron sulfide). The new compound (mineral) has different chemical and. physical properties from the elemental iron and sulfur out of which it was formed.
