The nitrogen in the gas which remains same in the inhaled and exhaled air. This answer is enough for all the practical purpose. You have asked the gases and not gas. so I have to add to the trace gases to the list. They are helium, neon, argon, crypton and xenon etcetera.
The composition of air expired is approximately 16% oxygen (O2) and 4% carbon dioxide (CO2), with the remaining 80% being nitrogen (N2) and trace gases.
because even though react due to high quantity they almost remain the same, so that is considered as a ideal gas.
air is the matter of gases because they are the same thing
Oxygen and Nitrogen are the two gases that do not condense when air is cooled to 200 degrees Celsius. They remain as gases at this temperature.
It will remain the same. (:
The quickest and most foolproof way to prove that air contains multiple gases is simply to isolate one and look at its behaviors, and, if the rest does not behave in the same manner, than it must be composed of other gases. For example, you could lower the temperture of a sample of air to zero degrees celsius, and the water in the air would freeze. However, the carbon dioxide, nitrogen, and other gases would remain gaseous, and, because they did not freeze, you could infer that different gases made up the remainder.
When the air temperature increases, the partial pressure of oxygen remains the same in the air. This is because the partial pressure of a gas in a mixture is determined by its concentration and is independent of the temperature, assuming the volume and moles of other gases remain constant.
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.

Appended is a list of gases with their specific gravities. The specific gravity of a gas is a comparison of its density with that of air at the same temperature and pressure. Gases with a Specific Gravity (SG) less than1 are lighter than air.
It is actually 43.22%. In my openion it is only .03 %
Expired air is breathed out though the nose or mouth, in volume it normally consists of: 78.04% Nitrogen.
