Question

Give two examples for each of the following types of mixture.
(a) solid-solid
(b) solid-liquid
(c) liquid-gas
(d) gas-gas

Answer 1

Hint: A mixture is created when two or more different substances are physically combined and can be separated back into their original substances. Examples of mixtures are a bowl of different kinds of candy, a pile of different kinds of leaves,

Complete answer:
The mixture is of two types homogeneous and heterogeneous. A homogeneous mixture is a mixture throughout the solution in which the composition is uniform. A heterogeneous mixture is a mixture with a non-uniform composition. The composition varies from one region to another with at least two phases that remain separate from each other, with clearly identifiable properties.

a) solid-solid mixture
This is the type of mixture which involves two or more solids. When the solids are metals, they are known as alloys.
Example: 1) sand and sugar, 2) sand and iron filling.

(b) solid-liquid
This is the mixture based on the combination of a solid and liquid substance. This is because the solid sometimes dissolves in the liquid.
Examples: 1) salt and water, 2) charcoal and water.

(c) liquid-gas mixture
This is a mixture formed with the combination of a liquid and a gas.
Examples: 1) coca-cola , 2) mist.

(d) gas–gas mixture
Gases are frequently encountered as mixtures. For example, the air we breathe is a mixture of several gases. It is mostly nitrogen and oxygen, but water vapour, argon, carbon dioxide, and various other gases are also present in small amounts.
Examples:
1. air
2. helium and hydrogen in air balloon,
3. perfumes and air.

Note: A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
