    Which colourless gas evolves when\[N{{H}_{4}}Cl\]reacts with zinc in a dry cell battery?

    A) \[N{{H}_{3}}\]                                  

    B) \[{{N}_{2}}\]

    C) \[{{H}_{2}}\]                                      

    D) \[C{{l}_{2}}\]

    Correct Answer: D

    Solution :

    \[{{H}_{2}}\]gas is evolved. When Zn reacts with \[N{{H}_{4}}Cl\]in dry cell battery. \[Zn+2N{{H}_{4}}Cl\xrightarrow[{}]{{}}Zn{{(N{{H}_{3}})}_{2}}C{{l}_{2}}+\underset{\begin{smallmatrix}  colourless \\  \,\,\,\,gas \end{smallmatrix}}{\mathop{{{H}_{2}}\uparrow }}\,\]
