Nitrogen dioxide - Wikipedia
https://en.wikipedia.org/wiki/Nitrogen_dioxide
WEBProperties. Nitrogen dioxide is a reddish-brown gas with a pungent, acrid odor above 21.2 °C (70.2 °F; 294.3 K) and becomes a yellowish-brown liquid below 21.2 °C (70.2 °F; 294.3 K). It forms an equilibrium with its dimer, dinitrogen tetroxide ( N2O4 ), and converts almost entirely to N2O4 below −11.2 °C (11.8 °F; 261.9 K).

WEBNitrogen dioxide is a deep red-orange gas that is poisonous but not flammable. It, along with aerosols, is responsible for the reddish-brown color of smog. At high concentrations it is highly toxic, and can cause serious lung damage. Nitrogen dioxide is a strong oxidizing agent, and is thus very reactive with other compounds.
