NO 2 of stikstofdioxide is een stof die vrijkomt bij verbrandingsprocessen. Lucht bestaat uit ongeveer 80% stikstof (N 2) en bij hoge temperaturen wordt dat door reacties met O 2 (zuurstof) geoxideerd tot NO (stikstofmonoxide) en deels ook in NO 2.NO wordt in de atmosfeer verder geoxideerd tot NO 2, een sterk "oxidans".Het kan voor irritatie zorgen aan ogen, neus en keel en kan bij

Nitrogen dioxide is a chemical compound with the formula NO 2. It is one of several nitrogen oxides. NO 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantity. Nitrogen dioxide is a paramagnetic, bent molecule with C2v
