MCQ
Pure ${N_2}$ gas is obtained from
- A$N{H_3} + NaN{O_2}$
- ✓$N{H_4}Cl + NaN{O_2}$
- C${N_2}O + Cu$
- D${(N{H_4})_2}C{r_2}{O_7}$
✓
Answer
Correct option: B.
$N{H_4}Cl + NaN{O_2}$
b
(b) $\underset{(aq)}{\mathop{N{{H}_{4}}Cl}}\,+\underset{(aq)}{\mathop{NaN{{O}_{2}}}}\,\,\to \,N{{H}_{4}}N{{O}_{2}}+NaCl$
(b) $\underset{(aq)}{\mathop{N{{H}_{4}}Cl}}\,+\underset{(aq)}{\mathop{NaN{{O}_{2}}}}\,\,\to \,N{{H}_{4}}N{{O}_{2}}+NaCl$
$N{{H}_{4}}N{{O}_{2}}\,\xrightarrow{\text{heat}}\,\underset{(g)}{\mathop{{{N}_{2}}}}\,+\underset{(l)}{\mathop{2{{H}_{2}}O}}\,$
