Question
Among the following compounds, which on heating do not produce $${N_2}?$$
A.
$${\left( {N{H_4}} \right)_2}C{r_2}{O_7}$$
B.
$$N{H_4}Cl + NaN{O_2}$$
C.
$$N{H_4}Cl + CaO$$
D.
$$Ba{\left( {{N_3}} \right)_2}$$
Answer :
$$N{H_4}Cl + CaO$$
Solution :
\[\begin{align}
& \left( \text{A} \right){{\left( N{{H}_{4}} \right)}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow{\Delta }C{{r}_{2}}{{O}_{7}}+{{N}_{2}}+{{H}_{2}}O \\
& \left( \text{B} \right)N{{H}_{4}}Cl+NaN{{O}_{2}}\xrightarrow{\Delta }N{{H}_{4}}N{{O}_{2}}+NaCl \\
& \left( \text{C} \right)2N{{H}_{4}}Cl+CaO\xrightarrow{\Delta }CaC{{l}_{2}}+2N{{H}_{3}}\uparrow +{{H}_{2}}O \\
& \left( \text{D} \right)N{{H}_{4}}N{{O}_{2}}\xrightarrow{\Delta }{{N}_{2}}\uparrow +2{{H}_{2}}O \\
& \,\,\,\,\,\,\,\,\,\,Ba{{\left( {{N}_{3}} \right)}_{2}}\xrightarrow{\Delta }Ba+3{{N}_{2}}\downarrow \\
\end{align}\]
