Air is generally considered a homogeneous substance because it is a mixture of gases that has a uniform composition throughout. The individual gases, such as nitrogen, oxygen, and carbon dioxide, are evenly distributed, making it difficult to distinguish the different components with the naked eye. However, in certain conditions, such as pollution or humidity, air can exhibit heterogeneous characteristics.
Pure air is homogeneous because all components are completely miscible.
homogeneous
CO2 is a pure substance and so is homogeneous. Hint: if it has a chemical formula then it is a pure substance.
heterogeneous and homogeneous is not the same so the substance is homogeneous and the mixture is heterogenous..
Homogenous mixture of two metals.

pure air is homogeneous but dusty air is heterogeneous
Pure Iron is considered as Homogeneous. Whereas, Iron with rust or other impurities is Heterogeneous.
