MCQ
${(N{H_4})_2}C{r_2}{O_7}$ on heating liberates a gas. The same gas will be obtained by
- ✓Heating $N{H_4}N{O_2}$
- BHeating $N{H_4}N{O_3}$
- CTreating ${H_2}{O_2}$ with $NaN{O_2}$
- DTreating $M{g_3}{N_2}$ with ${H_2}O$
✓
Answer
Correct option: A.
Heating $N{H_4}N{O_2}$
a
(a) ${(N{H_4})_2}C{r_2}{O_7}\xrightarrow{\Delta }{N_2} \uparrow + C{r_2}{O_3} + 4{H_2}O$
(a) ${(N{H_4})_2}C{r_2}{O_7}\xrightarrow{\Delta }{N_2} \uparrow + C{r_2}{O_3} + 4{H_2}O$
$N{H_4}N{O_2}\xrightarrow{\Delta }{N_2} \uparrow + 2{H_2}O$
