Answer 1

Answer:

Sulphur particles will be left in the dish after evaporation

when the mixture is shaken with carbon disulphide only sulphur dissolves to form a yellow coloured compound.

Common salt will not dissolve because it is a non-polar solvent.

When the mixtured is filtered through the filtered paper common salt,sand and iron fillings remains in the filtered paper.

Then the filtrate is evaporated to dryness and sulphur will be remained in the china dish after evaporation.
