Question

You are provided with a mixture of common salt and ammonium chloride

what is the name of the phenomenon

Answer 1

Answer:

the name of the phenomina is sublimation

Answer 2

It is a mixture.

It can be separated by a process called Sublimation. The ammonium chloride will vapourise and the common salt will be left. To obtain the ammonium chloride separately, we have to take an inverted funnel on a China dish, with the mixture. Heat it, and the ammonium chloride will vapourise and will get stuck in the narrow area of the funnel. And the common salt will stay back separately in the China dish.

Then you will get the common salt and ammonium chloride separately.

Hope it helped.
