Hello,
I'm a bit confused with the following question
I got part a but I'm a lil stuck with part b (and c).
For a, I got the charge will equal 4+ because according to the electrochemical series Sn ^4+ (aq) + 2 e- (those double sided arrows) Sn ^2+ (aq) so I just took that 4+ charge. Is that alright?
For part b, I attempted using Q= I x t
and I got...
25 * 18000 = 450 000 coulombs.
Then I would have to use Q= n (e-) x F... right??
So would I rearrange to find n(e-) = Q/F,
but then if I did that, what would I do about the 4:2 ratio?? would I divide by 2 or times by 2 or ...?
I'm not quite sure how to do part c either
I just started this topic today so I'm still a bit unsure about it.
Thank you
