Question

Air is an example of homogeneous mixture
A) True
B) False

Answer 1

Hint: Mixtures come in two overarching categories: heterogeneous mixtures and homogeneous mixtures.
A homogeneous mixture is simply any mixture that is uniform in composition throughout. As long as each substance is mixed in enough to be indistinguishable from the others, it is a homogeneous mixture.
A heterogeneous mixture is a mixture that does not have uniform composition throughout.

Complete step by step answer:
If a substance can be seen to contain two or more distinct components, it is considered heterogeneous. If it appears to be just one uniform substance, it is homogeneous.
Air is a homogeneous mixture of two or more components as it is made of gases that have uniform composition and are distributed uniformly throughout. The air that we breathe is a homogeneous mixture of oxygen, nitrogen, argon, and carbon dioxide, along with other elements in smaller amounts.
Air, neon, nitrous oxide, natural gas are all examples of homogeneous mixture.
Alloys, bitumen, cement, plastics, wood are all examples of homogeneous solid mixtures.
Liquid laundry Detergents, wine, liquors, blood plasma, milk, water are all examples of homogeneous liquid mixtures.
Therefore the statement is true.

So the correct option is A. True

Note:
If we consider some region of air, the gases present in one part of the region will have equal no. of moles as compared to another one part of the same region having the same volume. We won’t be able to visibly differentiate gases present in air.
