sulfur and iron are elements, sulfur a yellow powder and iron a metal. When mixed together at room temperature they do not react readily and constitute a mixture which can be separated say by using a magnet to attract the iron. Heat them up and a vigorous reaction ensues forming a chemical compound, black iron sulfide, Fe2S3 see link for experimental details
What else can I help you with?
Why can iron sulphide be classified as an element compound or a mixture?
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.
