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.
The iron and sulphur atoms are not joined together in the mixture, but they are joined together in iron sulphide. The iron and sulphur still behave like iron and sulphur in the mixture, but iron sulphide has different properties from both iron and sulphur.You can separate the iron from the mixture using a magnet but this does not work for iron sulphide.1  Page. 2  1. 3  2. 4  3. 5  4.he iron and sulphur atoms are not joined together in the mixture, but they are joined together in iron sulphide.
