Bookmark or Share- Nitronium ion - WikipediaThe nitronium ion, [ N O 2]+, is a cation. It is an onium ion because its nitrogen atom has +1 charge, similar to ammonium ion [NH4]+. It is created by the removal of an electron from the paramagnetic nitrogen dioxide molecule NO2, or the protonation of nitric acid HNO3 (with removal of H2O ). [2]
- The world's forgotten greenhouse gas - BBCScientists at the Intergovernmental Panel on Climate Change (IPCC) have estimated that nitrous oxide comprises roughly 6% of greenhouse gas emissions, and about three-quarters of those N2O ...
- Basic Information about NO2 | US EPANitrogen Dioxide (NO 2) is one of a group of highly reactive gases known as oxides of nitrogen or nitrogen oxides (NO x ). Other nitrogen oxides include nitrous acid and nitric acid. NO 2 is used as the indicator for the larger group of nitrogen oxides. NO 2 primarily gets in the air from the burning of fuel.
- WHO Guidelines for Indoor Air Quality: Selected Pollutants.There are seven oxides of nitrogen that may be found in the ambient air. Nitrous oxide (N2O) is a greenhouse gas with significant anthropogenic sources contributing to its worldwide abundance (∼ 0.3 ppm). However, nitric oxide (NO) and nitrogen dioxide (NO2) are the two principal nitrogen oxides associated with combustion sources. Ambient concentrations of these two gases vary widely ...
- Nitrogen Dioxide - an overview | ScienceDirect TopicsNitrogen dioxide (NO2) is one of a group of highly reactive gases known as nitrogen oxides (NO x ). NO 2 is the main source of nitrate aerosols, which form an important fraction of PM 2.5 and, in the presence of ultraviolet light, of ozone. The major sources of anthropogenic emissions of NO 2 are combustion processes.
