Answer 1

Answer:Iron mixes with sulphur which is physical change so we can seperate it by using a magnet

But when we heat this mixture iron reacts with sulphur to form iron sulphide which is a chemical change but we can seperate it by using carbon disulfide which dissolve the sulfur in it and we can filter the iron fillings by using filter paper and the filtrate will evaporate letting sulphur remain in the flask.
