Expert Answer:

Iron fillings are separated from the mixture by using a magnet. A magnet is moved on the surface of mixture. Iron fillings cling to the poles of the magnet and get separated.

Ammonium chloride is separated by sublimation. Heat the mixture of ammonium chloride and Sand in a china dish. By heating the mixture, ammonium chloride changes into vapours and is separated out. Sand does not change into vapours on heating, so it remains behind in the china dish.
