    \[N{{H}_{4}}Cl{{O}_{4}}+HN{{O}_{3}}(dil.)\xrightarrow{{}}HCl{{O}_{4}}+[X]\]\[\left[ X \right]\xrightarrow{\Delta }Y(g)\] [X] and [Y] are respectively-

    A) \[N{{H}_{4}}N{{O}_{3}}\And {{N}_{2}}O\]   

    B) \[N{{H}_{4}}N{{O}_{2}}\And {{N}_{2}}\]

    C) \[HN{{O}_{3}}\And {{O}_{2}}\]          

    D) \[{{N}_{2}}O\And {{H}_{2}}O\]

    Correct Answer: A

    Solution :

    \[{{\operatorname{NH}}_{4}}Cl{{O}_{4}}+HN{{O}_{3}}\to HCl{{O}_{4}}+N{{H}_{4}}N{{O}_{3}}\]                                                      \[{{\operatorname{NH}}_{4}}N{{H}_{3}}\xrightarrow{\Delta }{{N}_{2}}O+2{{H}_{2}}O\]
