Answer 2

Answer:

1. Common Salt + Iodine + Sulphur

Iodine can be separated by Sublimation

Salt can be separated by dissolving in water

now, sulphur is left...

2. Iron filling + Sulphur + Charcoal

Iron filling can be separated by using magnets

Sorry...no idea about seperation of charcoal and sulphur

3. Common Salt + Water + sawdust

Common salt will dissolve in water, so use filtration to separate sawdust first, then use evaporation technique to separate salt from water....

3. Mercury + water + nitre

due to high density, mercury will decent at bottom of water, so it can be easily separated...Sorry, no idea about nitre.
