mixture
No. Air is a mixture.
Air is a mixture of gases.
Air is a mixture, made mostly of the elements nitrogen and oxygen. It also has some other gases, such as argon (element), carbon dioxide (compound), and water (compound).
Water is the compound. Iodine and calcium are elements, and air is a mixture.
Foggy air is a mixture because it is composed of water droplets suspended in the air. It is not a pure substance with a fixed composition, so it does not qualify as an element or a compound.
mixture
Air is homogeneous mixture of gases.
Air (clean or dirty) is a mixture, as it contains several different gases.
Air is a mixture; the properties of the constituents of air (oxygen, nitrogen, carbon dioxide etc.) are not changed, and the mass ratios among them are not as consistent as they would be if air were a compound. On distillation of liquefied air, nitrogen predominantly distills off first, leaving behind oxygen in the liquid form. This is characteristic of a mixture, not of a compound.
Both are mixtures.
Water is a compound composed of hydrogen and oxygen atoms, while air is a mixture of gases primarily composed of nitrogen and oxygen. So, water is a compound, while air is a mixture.
Air is a gaseous mixture. (It has attributes of a compound because it cannot be separately physically by normal means, only by elaborate centrifuges or cooling.)
