Answer 2

Answer:

1. Mercury+ Water can be separated by decantation

2. chalk + water can be separated by filtration

Explanation:

1. Mercury and water are separated by decantation by using separating funnel as the separation of two immiscible liquids by a separating funnel depending on the difference in their densities. Mercury is heavier than water therefore, forms the lower layer and is separated from the water.

2. In chalk, you can separate the solid from the liquid by filtering the suspension through filter paper.
