In these conditions, some of the hydrogen and nitrogen will react to form ammonia. Stage four The unreacted nitrogen and hydrogen, together with the ammonia, pass into a cooling tank. The cooling ...

The equation shows that ammonium chloride (a white solid) can break down to form ammonia and hydrogen chloride. It also shows that ammonia and hydrogen chloride (colourless gases) can react to ...

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.

The precipitates will dissolve and darkly colored ammonia complexes will form. (Cobalt requires 6 times the cation volume to form the complex.) Use the other beakers or test tubes as references. Use ...

A white ring of solid ammonium chloride forms where the two gases meet inside the tube. If necessary, protect non-glass surfaces of an overhead projector with clear plastic. Dip one Q-tip into ...
