1. How long does it take for a current of (6.0A) to deliver (1.5×10^17 Cu^2+) ions in a solution? Assume these ions are the only charged particles moving.
I done:
I=Q/T
I = 6.0
Q = 1.5x10^17 Cu^(2+) = (1.5x10^17)(3.2x10^-19) C
I then done
T = Q/I
2. I haven't done this topic yet so it's completely a guess lol but since they are Cu 2+ ions wouldn't the charge double?

Yep , first it is neutral
2+ means it loses 2 electrons
So it has more protons by 2.
therefore there is a positive charge
One proton = 1.60x10^-19
Two = 3.20x10^-19
