Mechanistic studies including density functional theory (DFT) calculations revealed that a nucleophilic attack of ammonia on manganese imide complexes occurs to form a nitrogen-nitrogen bond leading to dinitrogen. To immobilize the contaminants and reduce their release into the environment . Manganese-catalyzed ammonia oxidation under chemical or electrochemical conditions is investigated in this work. Statistically, there is far more chance of an ammonia molecule hitting a hexaaqua metal ion than of hitting a hydrogen ion. This is a reversible reaction, so basically it can be used for preservation of hydrogen in a more compact ammonia form: 3 H 2 + N 2 2 NH 3 The downside of liquid ammonia is that it is toxic and suffocating. Oxygen is one of the most abundant elements found in Nature. In the present study a model of liver damage in rats was combined with ammonia and manganese exposure to evaluate the role of these substances separately and their . B.P.
