Question

All gas mixtures are _____. heterogeneous solutions heterogeneous compounds homogeneous multiple phases homogeneous solutions

Answer 1

All gas mixtures are homogeneous. You can not identify the different parts of the gas mixture as well as even see it!

Answer 2

Answer: The correct answer is homogeneous mixtures.

Step-by-step explanation:

Homogeneous mixtures are defined as the mixtures in which there is no physical separation between the dispersed medium and dispersed phase. The particles cannot be separated by physical means such as filtration.

Heterogeneous mixtures are defined as the mixtures in which a physical separation between the dispersed medium and dispersed phase is present. The particles can be easily separated by the physical means such as filtration.

All the gases mix up easily and no physical separation can be seen between the particles. Hence, these mixtures always form homogeneous mixture.

Thus, the correct answer is homogeneous mixtures.
