It combines with some of the moreactive metals such as lithium and magnesium toform nitrides, and at high temperatures it willalso combine with hydrogen, oxygen, and otherelements. It is used as an inert protection againstatmospheric contamination in many nonweldingapplications. Nitrogen is only ...
Electric DischargesNitridesSynthesisNitrogen activated by dark electric discharge combines with alkali metals to form azides. In the case of cesium, rubidium and potassium small amounts of nitrides are also formed which apparently are secondary products resulting from the primarily formed azides. This ...
Once in the ocean, some of the sulfur cycles through marine communities as it moves through food chains, some reenters the atmosphere, and some is lost to the ocean depths as it combines with iron to form ferrous sulfide (FeS), which is responsible for the black colour of marine sediments...
Nitric oxide, when inhaled, combines with hemoglobin to form nitrosohemoglobin, a carboxyhemoglobin-like material that rather rapidly is oxidized to methemoglobin. That is, its main effect is to inhibit transportation of oxygen by the blood. Its TLV and PEL are both 25 ppm. Nitrogen dioxide is...
Nitric oxide is more active than free nitrogen. For example, nitric oxide combines with oxygen and water in the atmosphere to make nitric acid. When it rains, nitric acid is carried to the earth. There it combines with metals in the Earth's crust. Compounds known as nitrates and nitrites ...
and is not life supporting. It combines with some of the more active metals such as lithium and magnesium to form nitrides, and at high temperatures it will also combine with hydrogen, oxygen, and other elements. It is used as an inert protection against atmospheric contamination in many non...
(40 or 30) = H20 + N03H.NH3 or N02H.NH3. The platinum suffers no permanent change; its mode of action probably consists in this that it alternately absorbs (i.e., combines with) oxygen and hands it over to the ammonia. In any case the reaction is interesting as throwing some ...
Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. Small amounts of nitrogen in steel inhibit grain growth at high temperatures and also increase the strength of certain steels. It can also be used to create a hard surface on steel. ...
(Fowler et al., 2013). Industry uses the Haber–Bosch process to fix atmospheric nitrogen to 1.6×1011kg of ammonia per year. It combines nitrogen and hydrogen at high temperature (400–600°C) and high pressure (20–40MPa) using an iron catalyst. This process is so energy intensive ...
