What is the energy conversion that occurs during the redox reaction in a Daniell cell?

Which of the following solutions cannot be used in a salt bridge?

Give the reactions for the following:
$(i)$ Reactions occurring at the electrodes and the overall redox reaction of a Daniell cell.
$(ii)$ Give the redox and electrode reactions of a $Cu-Ag$ galvanic cell.

What is the electrical work done by a galvanic cell?

An electrochemical cell is constructed using half-cells in the direction of spontaneous change: $Fe(OH)_{2}(s) + 2e^{-} \rightarrow Fe(s) + 2OH^{-}(aq)$ $(E^{0} = -0.88 \text{ V})$ and $AgBr(s) + e^{-} \rightarrow Ag(s) + Br^{-}(aq)$ $(E^{0} = +0.07 \text{ V})$. Which of the following options is correct?

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