Air is a mixture because it is easily separated into its component gases. If it was a compound you would have to perform complex operations like electrolysis to break the bonds between atoms in the compound...but with air, all you need do is cool the air enough to cause the gases to condense.
Water is the compound. Iodine and calcium are elements, and air is a mixture.
Compound
Air is a mixture of gases, primarily nitrogen (about 78%) and oxygen (about 21%), along with trace amounts of other gases like carbon dioxide and argon. Therefore, air is not an element or a compound, but a mixture of 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.
Exhaled air is a mixture of various gases, primarily nitrogen, oxygen, carbon dioxide, and traces of other gases like argon and water vapor. It is not a compound or element on its own, but rather a combination of different gases.
No. Air is a mixture.
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.
Concrete is a mixture of different substances (compounds) not a sinle compound.
mixture
Air is homogeneous mixture of gases.
Air (clean or dirty) is a mixture, as it contains several different gases.

Both are mixtures.
