Nitrogen dioxide is gaseous substance a brownish red, highly
active, also known as hydrogen peroxide.
Nitrogen dioxide is a reddish-brown gas above 70 °F (21 °C; 294 K)
with a pungent, acrid odor, becomes a yellowish-brown liquid below
70 °F (21 °C; 294 K), and converts to the colorless dinitrogen
tetroxide (N 2O 4) below 15 °F (−9 °C; 264 K).
