You could bubble it through limewater. One of them will react to form a precipitate and the other won't.
They also smell different, though I wouldn't necessarily recommend that method.
Oxygen = O2Nitrogen = N2Carbon Dioxide = CO2First to are diatoms and the third is a molecule of CO2
Carbon dioxide is a chemical compound with the formula CO2. It contains one atom of carbon and 2 atoms of oxygen and its molecular geometry is linear. It is a colorless gas formed by the combustion of carbon or carbon compounds. Nitrogen dioxide is a chemical compound with the formula NO2. It contains one atom of nitrogen and two atoms of oxygen and its molecular geometry is bent. It is a brown gas often formed by superheating air or by electrical arcs. Unlike CO2, NO2 exists in equilibrium with its dimer, N2O4
by breathing co2 back into the air. Therfore magically making it nitrogen.
CO2
Air is the mixture of different gases (like oxigen, nitrogen, co2 e.t.c.) & water vapour. Gases are only gases, here is no water vapour. And water vapour is form after the vapourization of water at high temperature.
The threads are different on Nitrogen tanks. There are adapters to use a Co2 gauge on a nitrogen bottle .

Nitrogen and co2
Halon, CO2, Neon,Nitrogen
The gaseous exchange that occurs in Lungs and effects differing levels of O2 and CO2 concentrations does not include N.
The percentage of expired air is around 74-80% Nitrogen. Because of gas exchange in the lung, expired air is also rich in CO2 and lower in O2 than atmospheric air (which has a 21.8% O2 comp and a .03 - .04% CO2 comp). Thus, the O2 and CO2 values narrow in difference to 14.5-16% and 4-5.5%, respectively.
Gasses are compressible and liquids and solids are incompressible. Using this information one can surmise that CO2 compressible would be the gas phase of CO2 and CO2 incompressible would be the solid (dry ice) phase of CO2.
No Nitrogen is
Usually CO2. Hydrogen and oxygen are fuels for fire. Nitrogen would work but is not usually used as it is too light.
