Yes
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.
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.

Oxygen is a pure substance because it is made up of only one type of atom - oxygen atoms. It is not a solution, which is a homogenous mixture of two or more substances.
Air is considered homogenous because it is a mixture of gases (primarily nitrogen and oxygen) that are evenly distributed throughout the atmosphere. This means that the composition of air is relatively consistent and uniform, with no noticeable variations in its properties in different locations or at different altitudes.

No it is not homogenous
homogenous.
All the elements are homogeneous so the oxygen is homogeneous, too.
Yes. Pure air is a homogenous mixture. Air is a mixture of various kinds of gases. A mixture is said to be homogenous when all its constituents are in phase. Example, a mixture of water & milk is a homogenous mixture, as water & milk both are liquids & are in phase. Same is the case with pure air. All the constituents gases of pure air are in phase with each other. Hence its a homogenous mixture.
