We would need to know the situation to be able to answer this question.
The nitrogen and hydrogen that don't react are recycled and put through the process again.
They react to form ammonia
yes
Formation of: - iron nitride, Fe2N - iron hydride, FeH or more correct FeHx
nitrogen gas and hydrogen gas
Hydrogen does not react with water
No, they do not react.
lt forms NH3
The helium and liquid hydrogen won't mix. The liquid nitrogen is not cold enough to cause the helium to liquify, and the helium is an inert gas and will not react with the nitrogen.
Ozone can react with atomic hydrogen at the temperature of liquid nitrogen forming the strange oxide H2O4.
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.
Sulfuric Acid ------- No. Nitrogen can be made to react with hydrogen under special conditions to make ammonia. This is done industrially using the Haber process.
