In present tokamaks nitrogen seeding is used to reduce the power load onto the divertor tiles. Some fraction of the seeded nitrogen reacts with hydrogen to form ammonia. The behaviour of ammonia in ASDEX Upgrade is studied by mass spectrometry. Injection without plasma shows strong absorption at ...
Lithium hydride is first reacted with nitrogen to form a mixture containing lithium nitride and/or lithium imide and/or lithium amide. These formed or formed lithium-nitrogen compounds are then reacted with hydrogen to form ammonia and again lithium hydride, which is recycled and reacts again ...
Suppose you react 16.9 grams of nitrogen gas with 16.9 grams of hydrogen gas. Determine the mass of ammonia that can be produced from these two reactants. For the following reaction, 4.27 grams of nitrogen gas is allowed to react with 5.04 grams of hyd...
hydrogen,or most other elements. Nitrogen will combine with oxygen, however, in the presence of lightning or a spark. The electrical energy from either of those sources causes nitrogen and oxygen to form nitric oxide:

Additionally automating the distillation step complicates things even further, so much so that many researchers have sought effective alternatives to the Kjeldahl method. One is on-line UV photo-oxidation in the presence of an oxidant such as hydrogen peroxide or sodium peroxydisulfate (the APHA ...
Nitrogen dioxide then reacts with water as follows: The nitric acid, HNO3, dissolves and comes to Earth with rain as a very dilute solution. In time it becomes part of the combined nitrogen of the soil, where it is neutralized, becoming nitrites and nitrates. The nitrogen content of ...
In the simplest amine, methylamine (CH3NH2), one hydrogen atom of ammonia has been replaced by a methyl group (Figure 12.2). The nitrogen atom of methylamine and other amines has five valence electrons in four sp3 hybrid orbitals that are directed to the corners of a tetrahedron. Three of...
However, the total Gibbs energy for ammonia formation favors the eNRR over hydrogen evolution. Also, an intrinsic challenge related to the low solubility of nitrogen (0.66 mmol L−1) and high concentration of water (55 mol L−1) in aqueous media limits the interaction of reactant nitrogen...
. The element isused in the Haber process for makingammonia and is also used to providean inert atmosphere in weldingand metallurgy. The gas is diatomicand relatively inert – it reacts withhydrogen at high temperatures andwith oxygen in electric discharges. Italso forms nitrides with certain...
