True. Air is considered a solution because it is a homogeneous mixture of gases, primarily nitrogen and oxygen, along with smaller amounts of other gases such as carbon dioxide and argon. In this mixture, the individual gas molecules are evenly distributed, which is characteristic of a solution.

21 is the only solution of that equation.

False. Liquid water in air forms a mixture, not a solution. A solution is a homogeneous mixture where one substance dissolves completely in another. In the case of water in air, the water droplets are dispersed throughout the air, but they do not dissolve in it.
