How many $L$ of chlorine gas will be deposited at $NTP$ when a current of $100 \, A$ is passed through molten $NaCl$ for $5 \, hours$?

Three electrolytic cells $A, B, C$ containing solutions of $ZnSO_{4}, AgNO_{3}$ and $CuSO_{4}$ respectively are connected in series. $A$ steady current of $1.5 \ A$ was passed through them until $1.45 \ g$ of silver deposited at the cathode of cell $B$. How long did the current flow? What mass of copper and zinc were deposited?

For the given reaction how much quantity of electricity in Coulomb is required? $\frac{2}{3} Al_2O_3 \rightarrow \frac{4}{3} Al + O_2$

When a current of $0.1 \, A$ is passed through $200 \, mL$ of a $0.1 \, N$ $AgNO_3$ solution,silver is deposited. How much time in $sec$ is required to remove half of the silver from the solution?

In an industrial process,$40 \ kg$ of calcium is produced by electrolysis in $2 \ hours$. How much $kg$ of aluminum would be produced if the same current is passed for the same duration? (Atomic mass of $Ca = 40, Al = 27$)

The electrochemical equivalent $Z$ of any element can be obtained by multiplying the electrochemical equivalent of hydrogen with
