The composition of air depends upon altitude.
gas composition in air is the sum of the gas individual element and that of the air i.e oxygen and nitrogen
Well, air contains 78.09% of Nitrogen, 20.95% of Oxygen, 0.03% of Carbon Dioxide and the rest of the gases like Argon, Helium, etc for about 1%. This composition of air is the same no matter where you go. If you're in Australia, the air will have this composition. If you're in South Africa, the air will have the same composition. The basic idea here is that the composition of air doesn't change which means air has a uniform composition. Homogeneous mixtures are those mixtures whose composition is same throughout the mixture and a heterogeneous mixtures are those mixtures whose composition is not same. Also, homogeneous mixtures are mixtures in which its components mix up thoroughly, i.e., the components cannot be observed whereas in a heterogeneous mixture, the individual components can be observed. In air, the Nitrogen or Oxygen cannot be observed separately. It is uniform and homogeneous. Thus, air is not a heterogeneous mixture.

Water and air
Both Inspired and expired air have higher amounts of oxygen than Carbon Dioxide. Inspired air has higher amounts of oxygen than expired, while expired air has higher amounts of Carbon Dioxide than inspired air.
The composition of air depends upon altitude.
The composition is the same, the air is just less dense.
gas composition in air is the sum of the gas individual element and that of the air i.e oxygen and nitrogen
Nitrogen is the most abundant gas in the atmosphere ( ~ 80% ) and therefore is the dominant species in both inspired as well as expired air.
no
The composition of liquid air is: 80 % nitrogen, 19 % oxygen 0,9 % argon, 0,1 % minor gases.
oxygen percentage in air is 20%
No.

Air composition can be measured in a variety of ways. The three most common ways are mixing ratio, number density, and partial pressure.
Yes there is go onto google images and type in 'pie chart for the composition if air' and it should come up.
