It depends on the kind of area you are talking about... but for a test I'd say Homogeneous meaning it is the same throughout.
Sorry, more to the point, eventually air will come to be homogeneous unless you have something that is not mixing like a level of smog or a rain cloud.
*For a test I'd still say Homogeneous, but it is a terrible question. Usually teachers tell you in their lectures or it is in your book, the answer that they want.
Air pollutants can be both homogeneous and heterogeneous. Homogeneous pollutants are evenly distributed in the air, such as carbon dioxide. Heterogeneous pollutants are not evenly distributed and can vary based on location, such as particulate matter near an industrial area.
Yes, air is considered a homogeneous mixture because it is made up of a combination of gases, such as nitrogen, oxygen, carbon dioxide, and others, that are uniformly distributed throughout. This means that the composition of air is consistent throughout its volume.
Sand with shells is a heterogeneous mixture because it contains different components (sand and shells) that are visibly different and can be separated easily. In a homogeneous mixture, the components are evenly distributed and not easily distinguishable.
Yes. It is a homogeneous mixture. It is a heterogeneous mixture. COLLOID because it does not settle but at the same time it makes stuff Smokey for example if you put a cup of water in a sun ray you may see little wavy things almost like hair flying in to the water and it sort of makes if foggy Dusty air is a suspension. The dust particles keep their shape. There is nothing in air to dissolve dust. mixture
Barium is an element and therefore a pure substance, so it is considered a homogeneous material.
pure air is homogeneous but dusty air is heterogeneous
Pure air is homogeneous because all components are completely miscible.
heterogeneous
homogeneous
Air is a homogeneous mixture.
Air is homogeneous mixture of gases.
Air is a homogeneous mixture.
Air is a homogeneous mixture.

yes
Depends on the quantity of air you are considering.
