Total pressure = ppO2 + ppH2 + ppN2
ppN2 = Total pressure - (ppO2 + ppH2)
ppN2 = 282 kPa - (110+106 kPa) = 282kPa - 216kPa
ppN2 = 66 kPa = partial pressure of nitrogen
Nitrogen and hydrogen react to form ammonia. This is the reaction in the Haber process, in which the gases are mixed at high pressure and moderately high temperature and passed over an iron catalyst.
These three components are the three largest components of air. The total pressure of a gas mixture is just the sum of the partial pressures of each component. Air is a mixture and nitrogen, oxygen, and argon are the three biggest components. So, the atmospheric pressure (or air pressure) would be the sum of the partial pressure of each component of the air: Ptot=PPnitrogen + PPoxygen+ PPargon = 442 mmHg + 118.34 mmHg + 5.66 mmHg = 566 mmHg
Over that modest range of pressures, Nitrogen gas could have a temperature of anything above approximately 80 degrees Kelvin (minus 193 degrees Celcius).
Nitrogen is an inert gas and is not necessary for breathing. Oxygen on the other hand is quite necessary. Without a sufficient partial pressure of oxygen in your breathing mix, you will become unconscious and if it is low enough, you can even die. For certain types of dives, nitrogen is reduced and sometimes completely removed from the breathing mix due to its narcotic effects at higher partial pressures. Dives have been done with helium and even hydrogen as substitutes for the nitrogen in the breathing mix due to their reduced narcotic effects at higher partial pressures. Not all insert gases work well though. Some are even more narcotic than nitrogen (e.g. argon, xenon).
Hydrogen, nitrogen, oxygen, fluorine, chlorine, and all the noble gases exist as a gas at standard temperature and pressure.

Carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
When the gases leave the reactor they are hot and at a very high pressure. Ammonia is easily liquefied under pressure as long as it isn't too hot, and so the temperature of the mixture is lowered enough for the ammonia to turn to a liquid. The nitrogen and hydrogen remain as gases even under these high pressures, and can be recycled. Another way is to add the water to the mixture (or pass the mixture from cold water) Ammonia is highly soluble in water but other two gases are not.
A standard temperature and pressure, they are gasses. However under different temperatures and pressures they can be plasmas, liquids and solids.
because in this process a mixture of nitrogen and hydrogen is heated at 400 to 450c
Over that modest range of pressures, Nitrogen gas could have a temperature of anything above approximately 80 degrees Kelvin (minus 193 degrees Celcius).
With the conditions of temperature and pressure found on the Earth hydrogen and oxygen in their free state are gas molecules consisting of two atoms. But nitrogen gas can also be found in this form.
when you go diving, you take a pressurized tank of air, air consists of about 79% Nitrogen and 21% Oxygen, at normal pressure (atmospheric pressuer) the partial pressure of Nitrogen is 0.79 Bar and Oxygen 0.21 Bar which is safe. Under high pressures (say 5 Bar which is at a depth of about 40 metres) the partial pressure of each gas increases Nitrogen (0.79x5=3.95Bar) which causes the lungs to absorb the nitrogen at a higher rate which influences the nervous system causing Narcosis (As if you're Drunk) The reason why you can't take a tank of oxygen instead of air is that oxygen becomes toxic at higher partial pressures
