Hi, so to solve for this, that's right first the half reaction at the cathode.
00:08
So we have here thin, so s and 2 plus, this is aqueous, and then the product will be thin.
00:17
That means we have here two electrons.
00:20
That's the balance equation.
00:23
We'll solve first for the number of moles of electrons that were transferred.
00:27
So for this, remember, columns is equal.
00:30
To current in terms of appears multiplied by time in terms of seconds.
00:40
Okay, so we'll multiply the given current.
00:43
That's 0 .876 and then the time is 56 .7 minutes.
00:52
So we'll convert minutes to seconds.
00:54
One minute is equivalent to 60 seconds, right? so we could cancel this.
01:00
And we'll get 2980 .152.
01:07
This is columns...
