$A$ current of $16\, A$ flows through molten $NaCl$ for $10\, min$. The amount of metallic sodium that appears at the negative electrode would be ............ $g$.

Which of the following represents the first law of Faraday?

Salts of $A, B$ and $C$ were electrolysed under identical conditions using the same quantity of electricity. It was found that when $2.1 \ g$ of $A$ was deposited,the weights of $B$ and $C$ deposited were $2.7 \ g$ and $9.6 \ g$. If the atomic mass of $A, B$ and $C$ are $7, 27$ and $64$ respectively,then the valencies of $A, B$ and $C$ respectively are:

If a current of $0.5 \ A$ is passed through a solution of $AgNO_3$ for $193 \ s$,$0.108 \ g$ of $Ag$ is deposited. What is the equivalent weight of $Ag$?

$A$ $250.0 \ mL$ 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 $Cr = 52$).

When a current of $2 \ A$ is passed through a molten salt of a metal for $5 \ hours$,$22.2 \ g$ of the metal (atomic mass $= 177$) is deposited at the cathode. What is the oxidation state of the metal in the molten salt?
