What substances can we separate using decantation? More than one option is correct. * - Sediments from metals -Liquids from sediments- Liquids of differente density- Metals from wood

b. Liquids from sediments.

c. Liquids of different densities

Explanation:

Decantation is a separation method in which a liquid layer of a mixture is separated. it is also used to separate two immiscible liquids. The upper layer is poured into another container during the separation process.

When there is a mix of a liquid and sediments, decantation can be used to obtain the decant. In addition if two liquids of different densities form a mixture, after some time the liquids separate and form a partition between them. The less dense liquid floats and could be decanted to separate it from the other liquid.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
