​

Answer 1

False

Explanation:

Chalk is insoluble - it does not dissolve in water.

Answer 2

Explanation:

the answer is:-

true,it mixes with water,but not completely.

Because when we crush the chalk the pieces or dust of chalk form. When mix this dust into water,the thiner and finer particles mix with water to give a slight white coloured solution but the particles which are heavier and bulkier than others settle at the base of the container in which the liquid is being made because of the heavier mass it has.

But as most of the particles mix with it,so the answer will be true.
