Calculate the amount of electricity required in coulombs to convert $0.08 \ mol$ of $MnO_4^{-}$ to $Mn^{2+}$. (in $C$)

How many electrons flow when a current of $5 \ A$ is passed through a cell for $200 \ s$?

When a current of $10 \ A$ is passed through molten $AlCl_{3}$ for $1.608 \ minutes$,the mass of $Al$ deposited will be [Atomic mass of $Al = 27 \ g/mol$]:- (in $g$)

An electric current is passed through silver nitrate solution using silver electrodes. $10.79 \ g$ of silver was found to be deposited on the cathode. If the same amount of electricity is passed through copper sulphate solution using copper electrodes,the weight of copper deposited on the cathode is ............. $g$

Alkanes can be prepared by the electrolysis of an aqueous solution of the potassium salt of a carboxylic acid (Kolbe's electrolysis). Find the total weight of all gases evolved at $STP$ by passing a $20 \ A$ current for $9650 \ s$ during the electrolysis of $CH_3COOK_{(aq)}$. [Ignore parallel or side reactions]

How much charge in Coulombs is required for the oxidation of $1 \ mol$ of $H_2O$ to $O_2$?
