which of the following is not a homogeneous mixture ? (a) smoke (b) air (c) brass (d) solution of sugar in water
Answers
Answer:
(a) Alloys are homogeneous mixtures, because they have a uniform composition throughout.
(b) No. solid solutions and gaseous solutions are also possible Examples brass and air respectively.
(c) No solution is always a homogeneous mixture of two or more substances.

Answer:
Correct option is: (a) smoke
Smoke is not a homogeneous mixture.
Explanation:
Smoke is not a homogeneous mixture because Smoke is heterogeneous mixture. We must understand that smoke is a term used to describe one of the products of a fire. It's actually a collection of particles with a diameter of less than five microns that float in the air. Smoke is a heterogeneous mixture because of this.
- Homogeneous solutions are those that have the same composition and properties throughout.
- Carbon atoms (solid phase) are dispersed into the atmosphere (gaseous phase).
- The composition of a homogeneous mixture is the same throughout its mass.
- There are no visible separation lines between the various constituents. For example, a sugar solution in water, a salt solution in water, a mixture of alcohol and water, and so on.
- A heterogeneous mixture of solids in a fluid/gaseous medium is referred to as smoke.
As a result, we can define smoke as a mixture of dispersed solid particles and gas as the dispersed medium, hence smoke is not a homogeneous mixture.
