Answer 1

Answer:

(D) both B and C

Chalk powder in water and Kerosene in water

Answer 2

The following is a heterogeneous mixture: (D) both B and C​

What is a mixture?

Two or more elements or compounds combine together to form a mixture. But, they retain their individual properties and no chemical reaction occurs between them.

Two types of mixtures are there as follows:

Homogenous mixture -

• In this type of mixture, a uniform composition of the substances is present.
• For example, solution of sugar in water

Heterogeneous mixture -

• In this type of mixture, the nonuniform composition of the substances present exists.
• For example, chalk powder and water. Chalk is insoluble in water, and hence heterogeneous mixture is obtained.
• Another example is a mixture of kerosene in water. Kerosene will form a separate layer as it is immiscible in water.
