For a lead storage battery, pick the correct statements:
$A.$ During charging of the battery, $PbSO_4$ on the anode is converted into $Pb$.
$B.$ During charging of the battery, $PbSO_4$ on the cathode is converted into $PbO_2$.
$C.$ The lead storage battery consists of a grid of lead packed with $PbO_2$ as the cathode.
$D.$ The lead storage battery has a $\sim 38\%$ solution of sulphuric acid as an electrolyte.

If $63.5 \ g$ of $Cu$ is deposited on the electrode from a $CuSO_4$ solution,what is the number of electrons involved?

The reduction potentials of four elements $P, Q, R,$ and $S$ are $-2.90 \ V, +0.34 \ V, +1.20 \ V,$ and $-0.76 \ V$ respectively. The order of decreasing reactivity is:

If the $\Delta G^o$ for the cell reaction $AgCl_{(s)} + \frac{1}{2} H_{2(g)} \rightarrow Ag_{(s)} + H^+ + Cl^-$ is $-21.52 \, kJ$,what will be the $\Delta G^o$ for the reaction $2AgCl_{(s)} + H_{2(g)} \rightarrow 2Ag_{(s)} + 2H^+ + 2Cl^-$ (in $, kJ$)?
