NOx (or NO x) refers to the sum of NO and NO2. [1][2] NOy (or NO y) refers to the sum of NOx and all oxidized atmospheric odd-nitrogen species (e.g. the sum of NOx, HNO3, HNO2, etc.)

NO+和N2是等电子体，显然其中的氮氧键属于三重键；NO2-的共振式，O=N-O (-)↔ (-)O-N=O，键级为 (2+1)/2=1.5；NO3-则和CO3 2-为等电子体，其键级为4/3。

氮氧化物指的是只由氮、氧两种元素组成的化合物，包括多种化合物，如一氧化二氮（N2O）、一氧化氮（NO）、二氧化氮（NO2）、三氧化二氮（N2O3）、四氧化二氮（N2O4）和五氧化二氮（N2O5）等。

2016年4月15日 · NO− 2, with two oxygens, since there is a 0 formal charge on nitrogen, then the oxygens each share a −1/2 charge (− 1 2 ×2 = −1 charge overall). NO− 3, with three oxygens, since there is a +1 formal charge on nitrogen, the remaining charge gets distributed onto all three oxygens, balancing out to be −2/3 per oxygen (− 2 3 × 3 +1 ...

化学式不同： 一氧化氮的化学式为NO，而二氧化氮的化学式为NO2。 气味不同： 一氧化氮为无色、无味的气体，而二氧化氮具有刺激性气味。

Nitric oxide (NO) plays an established role in numerous physiological and pathological processes, but the specific cellular sources of NO in disease pathogenesis remain unclear, preventing...

NO3 + NO = NO2 is a Synthesis reaction where one mole of Nitrate Radical [NO 3] and one mole of Nitric Oxide (Radical) [NO] combine to form two moles of Nitrogen Dioxide [NO 2]

2012年8月2日 · NO3-平面三角形其中N原子sp2杂化,有派4-6的大派键,键角120度,键长121pm,离子对称性很高. NO3-和NO2-各有什么性质，以及相互的联系和区别？ 联系:3HNO2=HNO3+NO+H2O2 MnO4- +5 NO2- + 6 H+ =2 Mn2+ + 5 NO3- +3H2O2 NaNO3加 …

NO2 is a reddish-brown gas at room temperature and pressure. It is highly reactive and soluble in water, forming nitric acid upon dissolution. NO2 is a major component of air pollution and is a precursor to the formation of smog and acid rain. In contrast, NO3 is typically found in the form of nitrate salts, which are solid compounds.
