B-Gas

Explanation:

Answer 2

Answer :

In the above question, given the separation of ammonium chloride and common salt, which is separated by the process of sublimation, as it is a solid-solid mixture.

Explanation :

Seperation technique :

On heating the mixtures, the solid that sublimes undergoes sublimation and changes to vapours on the cooler part of the funnel and then the vapour is cools to get the solid back. and and the solid in the mixture that do not sublime womens behind the evaporating dish.

Label A :

Label A denotes the solid ammonium chloride, which cools and from the vapour. On heating, white fumes are seen. These fumes then change back to solid ammonium chloride along the cooler upper part of the funnel as sublimate.

Label B :

Label B denotes a cotton wool which helps the stem of funnel to lock, which prevent the ammonium chloride vapour from escaping into the atmosphere.
