How do the ions transfer between solutions in an electrochemical cell?

Copper displaces which of the following metals from their salt solutions?

If $\Lambda _{NaCl}^{o}=126\,S\,cm^{2}mol^{-1}$,$\Lambda _{KBr}^{o}=152\,S\,cm^{2}mol^{-1}$,and $\Lambda _{KCl}^{o}=150\,S\,cm^{2}mol^{-1}$,then find $\Lambda ^{o}_{NaBr}$ in $S\,cm^{2}mol^{-1}$.

Explain the symbolic representation of a galvanic cell (electrochemical cell) with a suitable example.

Determine True $(T)$ or False $(F)$ :
$1.$ In a battery,the conversion of electric energy into chemical energy is carried out.
$2.$ Batteries are current-generating instruments.

Which of the following net cell reactions takes place in a galvanic cell containing a copper electrode and a standard hydrogen electrode $(SHE)$? Given: $E^{\circ}(Cu^{2+}_{(aq)} \mid Cu_{(s)}) = +0.34 \ V$.
