Note 3 — Chapter V · NITROGEN AND AIR
George Kamensky translation
The oxygen compounds of nitrogen (for example, N2O, NO, NO2) are decomposed at a red heat by themselves, and under the action of red-hot copper, iron, sodium, &c., they give up their oxygen to the metals, leaving the nitrogen free. According to Meyer and Langer (1885), nitrous oxide, N2O, decomposes below 900°, although not completely.
