A) \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{\text{O}}_{7}}\]
B) \[N{{H}_{4}}Cl+NaN{{O}_{2}}\]
C) \[N{{H}_{4}}Cl+CaO\]
D) \[Ba{{({{N}_{3}})}_{2}}\]
Correct Answer: C
Solution :
[c] [a] \[{{(N{{H}_{4}})}_{2}}C{{r}_{2}}{{O}_{7}}\xrightarrow{\Delta }C{{r}_{2}}{{O}_{7}}+{{N}_{2}}+{{H}_{2}}O\] [b] \[N{{H}_{4}}Cl+NaN{{O}_{2}}\xrightarrow{\Delta }N{{H}_{4}}N{{O}_{2}}+NaCl\] [c] \[2N{{H}_{4}}Cl+CaO\xrightarrow{\Delta }CaC{{l}_{2}}+2N{{H}_{3}}\uparrow +{{H}_{2}}O\] [d] \[N{{H}_{4}}N{{O}_{2}}\xrightarrow{\Delta }{{N}_{2}}\uparrow +2{{H}_{2}}O\] \[Ba{{({{N}_{3}})}_{2}}\xrightarrow{\Delta }Ba+3{{N}_{2}}\downarrow \]
