air is a mixture of elements (nitrogen, oxygen, trace amounts of other elemental gases) plus compounds (water vapor, nitrogen and sulfur oxides, CO2)
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.
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.)
Reactants can be a mixture, compounds, a mixture of compounds and also elements. It depends on the reaction. Air is a mixture and is often a reactant for example.
No. Air is a mixture.

Yes, the mixture is called air.
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).
No. The air we breathe is a homogeneous mixture of gases, not a compound. Nitrogen gas (N2) makes up about 78% and oxygen gas (O2) makes up about 21%. The other 1% is made up of many different gases, including carbon dioxide gas (CO2) and hydrogen gas (H2). For a chart showing the complete composition of the air, see the related link below.
Water is the compound. Iodine and calcium are elements, and air is a mixture.
is heterogenous because it is composed of many different gases. To be homogenous it would have to be composed of a single gas.
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.
Yes, we breathe in a mixture of gases that includes nitrogen, which makes up about 78 of the air we inhale.
