Air is an example of a homogeneous mixture because its components (nitrogen, oxygen, argon, etc.) are uniformly distributed throughout, giving it a uniform composition and properties throughout.
Pure air is considered a homogenous mixture because its components (nitrogen, oxygen, carbon dioxide, etc.) are uniformly distributed throughout and indistinguishable from one another at a molecular level.
It is a gaseous mixture containing 75% oxygen and 25% helium by volume.
It's a compound. H2O - Two hydrogen atoms, one oxygen atom Water is a compound as it can be reduced to simpler elements (Oxygen and water).It is a homogenous mixture("the same") as it is uniform throughout. E.g: Salt and sand mixed together would be a heterogenous mixture("different") as you can distinguish between sand and salt. A pure 'mixture' is usually homogenous, especially liquids.
Oxygen is not known as helium. But a mixture of oxygen and helium is used in the oxygen cylinder for underwater diving.
AnswerIt is heterogeneous as it is made up of many different atoms and molecules... carbon, hydrogen, oxygen as well as pollen and pollutants.Air is a homogenous mixture.

No, oxygen is an element.

Heterogeneous. It's a combination of two homogenous substances - hydrogen, and oxygen. What you're describing is hydrogen peroxide, by the way.

Air is considered a solution because it consists of gases such as nitrogen, oxygen, and carbon dioxide dissolved within each other. This mixture of gases forms a homogenous mixture, similar to how a solution is a homogenous mixture of two or more substances.
Mixtures may be either homogenous (evenly distributed) or heterogenous (unevenly distributed). Where one substance is dissolved within another, it is not a mixture but a solution. "Colloids" or suspensions (such as milk) are generally homogenous although they may be considered heterogenous if the particles are large in size or clumped. Examples of heterogenous mixtures would be common dirt, which contains many different compounds unevenly dispersed. An example of a homogenous mixture would be nitrogen and oxygen in air, where local, circulating air will contain equally proportional amounts of each gas. At high altitude, the proportion is the same but there are fewer molecules of each gas.
A substance can be either of them all.The substance ........ water is a compound.... gin is a homogenous mixture (of mainly two compounds: alcohol and water).... milk is a heterogenous mixture of three: water, protein, fat.... gold is a solid element, .... mercury is a liquid element and.... oxygen is a gaseous element.
