dinitrogen pentoxide
Chemistry; Atmospheric chemistry
N 2 O 5 , a compound that contributes to ozone depletion during springtime in the Antarctic. This occurs because ozone converts some nitrogen dioxide radical to nitrogen trioxide ...
photochemical smog
Chemistry; Atmospheric chemistry
Natural and artificially emitted hydrocarbons in the presence of oxides of nitrogen undergo photochemical reactions which produce a cloud of toxic chemicals including ozone and a ...
ozone distribution
Chemistry; Atmospheric chemistry
Nearly all of the planet's natural ozone in the atmosphere is found in the stratosphere. The thickness and distribution of this stratospheric ozone vary seasonally and by ...
