The nitrogen oxides that contain N – N bond(s) is:

Q. The nitrogen oxide(s) that contain(s) $N-N$ bond(s) is/are

Q. Pure $N_2{O}_3$ exists only in the solid state at low temperature. Above its melting point, it dissociates to

Q. When $N_2{O}_5$ is heated at temp. T, it dissociates as $N_2{O}_5\rightleftharpoons N_2{O}_3+O_2,K_c=2.5$. At the same time $N_2{O}_3\rightleftharpoons N_{2}O+O_2$. If initially 4.0 moles of $N_2{O}_5$ are taken in 1.0 litre flask and allowed to attain equilibrium, concentration of $O_2$ was formed to be 2.5 M. Equilibrium concentration of $N_{2}O$ is:

Q. How many of the following compounds has XX bonds i.e. single covalent bond between two same elements in their molecules :
$H_2{S}_2{O}_4,H_2{S}_2{O}_7,H_2{S}_2{O}_8,N_{2}O,N_2{O}_3,N_2{O}_4,N_2{O}_5,{\left(HP{O}_3\right)}_3$

Q. When $N_2{O}_5$ is heated at temperature T, it dissociates as $N_2{O}_5\rightleftharpoons N_2{O}_3+O_2,K_e=2.5$. At the time $N_2{O}_3$ also decomposes as: $N_2{O}_3\rightleftharpoons N_{2}O+O^2$. If initially $4$ moles of $N_2{O}_5$ are taken in $1$ litre flask and allowed to attain equilibrium, concentration of $O_2$ was formed to be $2.5M$. Equilibrium concentration of $N_{2}O$ is:
