BRAINCAKEOxides of Nitrogen
Oxides of nitrogen, written together as NOx, are pollutants from vehicle engines and power stations.
Unlike sulfur dioxide, they do not come from impurities in the fuel. The nitrogen and oxygen both come from the air. Nitrogen is very unreactive because of its strong N≡N triple bond, but the very high temperature and the spark in an engine provide enough energy for it to react:
N2 + O2 → 2NO
