Ammonia is currently obtained by reacting nitrogen (N2) from air with hydrogen (H2). This reaction requires high energy and is, therefore, powered by fossil fuels, contributing to over 3% of the ...

Atmospheric nitrogen, with the aid of an iron catalyst, reacts with hydrogen to produce ammonia. That reaction produces lots of ammonia – worldwide production is 160 million tons every year.

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: ...
