329914 Following are some of the facts about dry cell
i) It is also called Leclanche cell
ii) It is also called Daniel cell
iii) Electrolyte is a moist paste of \({\rm{N}}{{\rm{H}}_{\rm{4}}}{\rm{Cl}}\,\,{\rm{and}}\,\,{\rm{ZnC}}{{\rm{l}}_{\rm{2}}}\)
iv) Cathodic reaction is
\({\rm{Mn}}{{\rm{O}}_2}(s) + NH_4^ + (aq) + {e^ - } \to MnO(OH) + N{H_3}\) Select correct facts:

329910 Assertion :
Dry cell is an example of primary battery.
Reason :
In the primary batteries, the reaction occurs again and again.

329919 In the button cell widely used in watches and other devices the following reaction takes place:
\({\rm{Z}}{{\rm{n}}_{{\rm{(s)}}}}{\rm{ + A}}{{\rm{g}}_{\rm{2}}}{{\rm{O}}_{{\rm{(s)}}}}{\rm{ + }}{{\rm{H}}_{\rm{2}}}{{\rm{O}}_{{\rm{(1)}}}} \to {\rm{Zn}}_{\,\,{\rm{(aq)}}}^{{\rm{2 + }}}{\rm{ + 2A}}{{\rm{g}}_{{\rm{(s)}}}}{\rm{ + 2OH}}_{\,\,\,{\rm{(aq)}}}^{\rm{ - }}\)
