Which of the following describes a homogeneous mixture? a. it can be separated by chemical means but not by physical means. b. it cannot be separated by either chemical or physical means. c. it can be separated by physical means and is uniform in composition. d. it can be separated by physical means and is not uniform in composition.

The correct answer is option c.

Explanation:

Homogeneous mixtures  : It is a mixture that appears uniformly throughout the solution and the particle size or shapes are not different. They can be separated by means of physical method.

For example : salt in water, alloys etc.

Heterogeneous mixtures  : It is a mixture that appears non-uniformly throughout the solution and the particle size or shapes are also different. They can be separated by means of physical method.

For example : sand in water, cereals in milk etc.

So, the correct answer from the given options is option c.
