Description:
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).
