When an electric current is passed through acidulated water,$112 \ mL$ of hydrogen gas at $N.T.P.$ collects at the cathode in $965 \ seconds$. The current passed,in amperes,is:

The amount of silver deposited by passing $241.25 \ C$ of charge through a silver nitrate solution is

During the electrolysis of an electrolyte,the number of ions produced is directly proportional to the

$A$ $250.0 \ mL$ sample of a $0.20 \ M \ Cr^{3+}$ is electrolyzed with a current of $96.5 \ A$. If the remaining $[Cr^{3+}]$ is $0.1 \ M$,the duration of the process is $............. \ s$ (Atomic weight of $Cr = 52$).

$A$ silver cup is plated with silver by passing $965 \ C$ of electricity. The amount of silver deposited is ............. $g$.

When the same quantity of electricity is passed through aqueous solutions of $AgNO_3$ and $CuSO_4$,if the number of atoms of $Ag$ and $Cu$ deposited are $x$ and $y$ respectively,then determine the correct relationship.
