Air can be separated into its constituent parts, some easily others not so easily. When this is done the gases exhibit different physical and chemical properties.
The most compelling evidence is the fact that it rains. Water evaporates from the oceans, and becomes vapor - a gas. Thus the air is a mixture of gasses, including water vapor. Eventually the water vapor condenses into liquid water, and rains.
It is a mixture of air with one or more other gases.
No. It will be a homogeneous mixture of gases.
Air is a heterogenous mixture because it is composed of different gases like oxygen, nitrogen, carbon dioxide, and others that do not combine chemically. Each of these gases retains its own properties within the air mixture.
Neither. It is a mixture.
Air (clean or dirty) is a mixture, as it contains several different gases.
Air is a mixture of gases.
Air is a mixture of gases.

It is a mixture of air with one or more other gases.
It is a mixture of air with one or more other gases.
A mixture of many gases is commonly known as air. Air is composed of different gases such as nitrogen, oxygen, carbon dioxide, and others in varying proportions.
No. It will be a homogeneous 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).
Air is a mixture of several gases, most notably nitrogen, oxygen, and some trace gases (eg, argon).
air is a mixture of gases, water vapour, dust particles and smoke the atmosphere is a mixture of colourless, odourless and tasteless gases
Gases, and so air which is a mixture of gases (at normal temperature and pressure) are not magnetic.
Air isn't a pure substance, it is a mixture of a bunch of other gases mainly Nitrogen and Oxygen with small amounts of other gases.
