The heating of NH_4 NO_2 at 60-70^ C and NH_4 NO_3 at 200-250^ C is...

The heating of

\mathrm{NH}_4 \mathrm{NO}_2

at

60-70^{\circ} \mathrm{C}

and

\mathrm{NH}_4 \mathrm{NO}_3

at

200-250^{\circ} \mathrm{C}

is associated with the formation of nitrogen containing compounds

\mathbf{X}

and

\mathbf{Y}

, respectively.

\mathbf{X}

and

\mathbf{Y}

, respectively, are

Options

A $\mathrm{N}_2$ and $\mathrm{N}_2 \mathrm{O}$
B $\mathrm{NH}_3$ and $\mathrm{NO}_2$
CNO and $\mathrm{N}_2 \mathrm{O}$
D $\mathrm{N}_2$ and $\mathrm{NH}_3$

Correct answer

A. $\mathrm{N}_2$ and $\mathrm{N}_2 \mathrm{O}$

Step-by-step solution

\begin{aligned} & \mathrm{NH}_4 \mathrm{NO}_2 \xrightarrow[60-70^{\circ} \mathrm{C}]{\Delta} \mathrm{N}_2+2 \mathrm{H}_2 \mathrm{O} \\ & \mathrm{NH}_4 \mathrm{NO}_3 \xrightarrow[200-250^{\circ} \mathrm{C}]{\Delta} \mathrm{N}_2 \mathrm{O}+2 \mathrm{H}_2 \mathrm{O}\end{aligned}
