When hydrogen is burned in air, the oxygen combines with the hydrogen leaving nitrogen behind. In addition, any unreacted nitrogen and hydrogen are recycled. The reaction is reversible.

ammonium nitrate and ammonium sulfate – can be identified by heating a solution of the ions with sodium hydroxide. This reaction produces ammonia gas, as shown in the ionic equation below: ...

e-during reactions and hydrogen poisoning-which reduces catalytic activity through the absorption to the active sites on Ru at elevated hydrogen pressure-does not occur. This delineated a path toward ...
