On passing $0.5 \ F$ of electricity through $NaCl$,the amount of $Cl_2$ gas deposited at the anode is .............. $g$.

$A$ solution of $Fe_{2}(SO_{4})_{3}$ is electrolyzed for '$x$' min with a current of $1.5 \ A$ to deposit $0.3482 \ g$ of $Fe$. The value of $x$ is $.......$. [nearest integer]
Given : $1 \ F = 96500 \ C \ mol^{-1}$
Atomic mass of $Fe = 56 \ g \ mol^{-1}$

How much chlorine will be liberated on passing $1 \ A$ current for $30 \ minutes$ through $NaCl$ solution?

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:

How much electricity in terms of Faraday is required for the reduction of $2 \ mol$ of $Cr_2O_7^{2-}$ into $Cr^{3+}$ in an acidic medium (in $F$)?

What is the quantity of electricity required to produce $4.8 \ g$ of $Mg$ (molar mass $= 24 \ g \ mol^{-1}$) from its salt solution (in $F$)?
