It is a mixture of all the gasses in the atmosphere and water.
It is a mixture.
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
The pure nitrogen is a chemical element, gaseous at room temperature.
O3 is a molecule / compound, not element
Air is a mixture of about 80% nitrogen, and about 20% oxygen, with small amounts of other substances (such as carbon dioxide and water vapor).
It is a solution of several gasses, the most abundant of which are nitrogen and oxygen.
Air is a mixture of gases.
It 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).
Air is mostly composed of elemental substances or molecules. It is also called as a mixture of compounds and elements.Air is not a compound, but it isn't a particular element. Air is a mixture of gasses that do not react with each other.
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
Both are mixtures.
Air (clean or dirty) is a mixture, as it contains several different gases.
Neither. Air is a mixture. Also, whether something is a compound or an element does not depend on temperature.
Both are mixtures.
Clean air is actually a mixture! It is made out of various elements such as oxygen, hydrogen and nitrogen.
Neither. Oxygen is an element. In the air it forms a mixture with nitrogen, carbon dioxide, etc.
Air is a mixture, because its elemental composition is not constant but instead varies with circumstances.
