    A)  Ammonium nitrate

    B)  \[N{{O}_{2}}\]

    C)  \[NO\]

    D)  \[{{N}_{2}}O\]

    Correct Answer: A

    Solution :

    \[Zn\]react with very dil. \[HN{{O}_{3}}\] and form zinc nitrate \[Zn(N{{O}_{3}}){{ & }_{2}},\]\[N{{H}_{4}}N{{O}_{3}}\] and\[{{H}_{2}}O\]. \[4Zn+10HN{{O}_{3}}\xrightarrow{{}}4Zn{{(N{{O}_{3}})}_{2}}\]\[+N{{H}_{4}}N{{O}_{3}}+{{H}_{2}}O\]
