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: ...

methane and ammonia. Recent experiments suggest that those sprays of water may have helped jump-start chemical reactions that produced the building blocks of life. According to Stanford University ...

They exposed synthetic iron-rich minerals to nitrogen-laced water, triggering a chemical reaction that oxidized the rock and yielded ammonia, which the team dubbed "geological ammonia." ...
