Question

answer it correct....? ​

Answer 1

Answer:

(I) Butler from curd.

Explanation:

(i) Butter from curd can be separated by the technique of centrifugation. (ii) Salt from sea water can be separated by the technique of crystallization or by the evaporation. (iii) Camphor is sublimable but salt is not. So, camphor can be separated from salt sublimation technique.

Answer 2

Answer:

I) Butter from curd is separated by the technique of centrifugation. The instrument used for the process of centrifugation consists of a rotor and is called centrifuge.

ii) The salt can be separate from sea water by distillation. We need to boil and evaporate that water and salt will be remain as solid. Then to collect water you can use diatillation because water has much less boiling point than salt.

iii) Sublimation is a technique used to separate the components of a mixture containing a sublimable volatile solid and a non-sublimable impurity. Therefore, the mixture of camphor and sodium chloride can be separated by the process of sublimation.
