Answer 2

Explanation:

False

It can be separated by physical change

here is how?

take a container and fill it with water. Add NaCl in the water and start heating it .After evaporation salt will be deposited on the bottom of the container. and we can collect chlorine vapours by placing the reversed funnel over the beaker and a cotton bud over it and when the water with NaCl starts heating Chlorine vapours will deposite in the cotton bud and after cooling the chlorine vapours it will be conversed in the chlorine

hence we can separate NaCl by physical method and it is reversible also
