In the reaction above, calculate the quantity of electricity required to discharge zinc.
[F = 96 500 C mol-1]
In the reaction above, calculate the quantity of electricity required to discharge zinc.
[F = 96 500 C mol-1]
0.965 x 104C
4.820 x 104C
9.650 x 104C
48.200 x 104C
Εξήγηση
1 mol → 96500 x 2
0.5 mol → X
X = 0.5 x 96500 x 2
= 9.650 x 104C
0.5 mol → X
X = 0.5 x 96500 x 2
= 9.650 x 104C
