What are reasonable sources of Hydrogen and Nitrogen?

Question

the haber process requires nitrogen and hydrogen, what are reasonable sources of both these elements.

Answer 1

The best source of cheap N2 is air. The way it's produced is as follows: Air is liquified by cooling it and compressing it. The liquid air then undergoes fractional distillation. That's where the various components are separated by means of their different boiling points (the approximate composition of air is, N2 = 78%, O2 = 21%, Ar = 0.9%, miscellaneous gases = 0.1%). In the laboratory, very pure N2 can be produced by heating sodium azide: 2NaN3 => 2Na + 3N2.
H2 can be made by the electrolysis of water: 2H2O => 2H2 + O2, or by the catalytic decomposition of hydrocarbons. In the lab, it's often made by reacting certain metals with a dilute acid, eg: Zn + H2SO4 => ZnSO4 + H2. H2 is also sometimes made by decomposing an active metal hydride with water, eg: CaH2 + H2O => Ca(OH)2 + H2. This method has been used to generate H2, on-site, for filling weather balloons. H2 is also made (along with CO) by reacting carbon (usually as coke) with very hot steam: H2O + C => H2 + CO. The mixture of H2 & CO is called "producer gas," and used to be used for gas heating, lighting, etc, before natural gas was readily available. Also, CO reacts with H2O at high temp. to produce "water gas": CO + H2O => H2 + CO2, which is a source of H2, if the CO2 is removed.

Answer 2

The air we breath is 80% nitrogen. Water is two thirds hydrogen.

Answer 3

Water for hydrogen and air for nitrogen

Answer 4

Nitrogren is usually distilled from the air after it is super-cooled.

Hydrogen can be obtained from water, but it is very expensive. Hydrogen is more easily obtained from several oxidation-reduction reactions that evolve hydrogen gas from the cathode (reduction).
