Question

Why is a gas in gas mixture always said to be a homogenous mixture?

Answer 1

There is a large amount of intermolecular space between the gas molecules. When two gases are mixed, particles of one gas can easily pass through the intermolecular space of the other gas. As a result both the gases get completely and evenly mixed forming a homogeneous mixture.
