Air (clean or dirty) is a mixture, as it contains several different gases.
Neither. Oxygen is an element. In the air it forms a mixture with nitrogen, carbon dioxide, etc.
Air is a mixture of different gases, including nitrogen, oxygen, carbon dioxide, and others, rather than a compound or element. It is not a pure substance but a combination of gases that makes up Earth's atmosphere.
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.
If you are talking about the gas we breath in the air, it's a compound. Pure oxygen as a gas exists as a molecule. Oxygen as an element, is unstable and as far as I know doesn't exist as a single element in nature. It will always occur in combination with something else, such as H2O or O2.
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).
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Smog is not an element or a compound. It is a type of air pollution that consists of a mixture of smoke and fog.
It is a mixture of all the gasses in the atmosphere and water.
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 (clean or dirty) is a mixture, as it contains several different gases.
Both are mixtures.
Water is the compound. Iodine and calcium are elements, and air is a mixture.
Pure air is an elemental mixture of different types of gases and so it is a homogeneous mixture from gases.
Air is neither an element nor a compound. It is a mixture of different gases such as oxygen, nitrogen, and carbon dioxide.
Neither. Oxygen is an element. In the air it forms a mixture with nitrogen, carbon dioxide, etc.
