MCQ
Among the following compounds, which on heating do not produce $N_2$ ?
- A$(NH_4)_2Cr_2O_7$
- B$NH_4Cl +NaNO_2$
- ✓$NH_4Cl + CaO$
- D$Ba(N _3)_2$
✓
Answer
Correct option: C.
$NH_4Cl + CaO$
c
$\mathrm{NH}_{4} \mathrm{Cl}+\mathrm{NaNO}_{2} \longrightarrow \mathrm{NH}_{4} \mathrm{NO}_{2}+\mathrm{NaCl}$
$\mathrm{NH}_{4} \mathrm{Cl}+\mathrm{NaNO}_{2} \longrightarrow \mathrm{NH}_{4} \mathrm{NO}_{2}+\mathrm{NaCl}$
$ \mathrm{NH}_{4} \mathrm{NO}_{2} \stackrel{\Delta}{\longrightarrow} \mathrm{N}_{2} \uparrow+2 \mathrm{H}_{2} \mathrm{O}$
$\mathrm{Ba}\left(\mathrm{N}_{3}\right)_{2} \longrightarrow \mathrm{Ba}+3 \mathrm{N}_{2} \downarrow$
$2 \mathrm{NH}_{4} \mathrm{Cl}+\mathrm{CaO} \longrightarrow \mathrm{CaCl}_{2}+2 \mathrm{NH}_{3} \uparrow+\mathrm{H}_{2} \mathrm{O} $
