Question

A gas bulb is filled with $N{O}_2$ gas and immersed in an ice bath at $0^{o}C$ which becomes colourless after some time. This colourless gas will be:

• A. $N{O}_2$
• B. $N_{2}O$
• C. $N_2{O}_4$
• D. $N_2{O}_5$

Answer 1

The correct option is C $N_2{O}_4$

A gas bulb is filled with $N{O}_2$ gas and immersed in an ice bath at $0^{o}C$ which becomes colourless after some time and then a colorless gas will be released which is $N_2{O}_4$.

Hence option C is correct answer.
