Question

Classify each of the following as a compound, a homogeneous mixture, or a heterogeneous mixture: (a) distilled water; (b) gasoline; (c) beach sand; (d) wine; (e) air.

Answer 1

Explanation:

A mixture which shows presence of uniform composition of solute particles into the solvent is known as a homogeneous mixture.

• Distilled water is a clear solution in which there is uniform composition of solute particles into the solution.

• Gasoline is mixture of different compounds which are evenly distributed. Therefore, it is also a homogeneous mixture.

• Wine is also a clear solution in which particles are evenly distributed. Hence, it is a homogeneous mixture.

On the other hand, a mixture which shows non-uniform composition of solute particles into the solvent is known as a heterogeneous mixture.

• Beach sand is a mixture of different particles present in varying composition. Hence, it is a heterogeneous mixture.

• Also, in air there are different gases present in different composition. Mover over, there is presence of fog and smoke into the air. Hence, it is a heterogeneous mixture.
