It takes 107 minutes 22 seconds and 96500 coulombs of charge produce 20.2 g of calcium.
The balanced equation for the reaction is,
The half-reaction of calcium is,
Mass of calcium = 20.2 g
The molecular mass of calcium = 40 u.
The number of moles calcium are,
One mole of Calcium is produced by 2 moles of electrons.
So, 0.5 moles of Calcium produce,
The charge required to produce 202 g of calcium is,
Current = 15 A
The time taken to produce 20.2 g of calcium is,
Therefore, 96500 columns of charge are required to produce 20.2 grams of calcium. And it takes 107 minutes and 22 seconds.
