2 amperes of current is passed for 16 min and 5 second through 1000 ml of 2 molar aqueous solution of `CuSO_(4)` using Pt electrodes. Then
A. `1.2046xx10^(22)` electrons are passed from anode to cathose
B. `0.635 g` of Cu is deposite at cathode
C. After the electrolysis process, when methyl orange is added to the residual solution, it gives yellow colour
D. The volume of `O_(2)` gas liberated at anode is equal to the `O_(2)` liberated by the decomposition of 56 ml of 2 volume `H_(2)O_(2)` solution at STP
