NOx is a generic term for the mono-nitrogen oxides NO and NO 2 (nitric oxide and nitrogen dioxide). They are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures.In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted into the atmosphere as air pollution can be significant.hey are produced from the reaction among nitrogen, oxygen and even hydrocarbons (during combustion), especially at high temperatures.

Manganese(IV) oxide (manganese dioxide, MnO 2) is used as a reagent in organic chemistry for the oxidation of benzylic alcohols (i.e. adjacent to an aromatic ring). Manganese dioxide has been used since antiquity to oxidatively neutralize the greenish tinge in glass caused by trace amounts of iron contamination.n 2+ often competes with Mg 2+ in biological systems. Manganese compounds where manganese is in oxidation state +7, which are restricted to the unstable oxide Mn 2 O 7 and compounds of the intensely purple permanganate anion MnO 4 â , are powerful oxidizing agents.
