Please don't change screen names. Lucy, John Butch, etc won't cut it. We can help better if we can keep one name.
For the Bi half, Bi on the left has an oxidation number of +3 and on the right is 0 so that is a gain of 3e and the 3e goes on the right. That's how you do that part. For the Sn half, on the left Sn is +2 and on the right it is +4 so 2e goes on the left. I can help with these but you need to be explicit about what you don't understand. As for the John Butch post, I'll ignore it.
After balancing the following redox equation(using small whole-number coefficients), add the coefficients of all species in the balanced equation.
Bi(OH)3 + SnO2^(2-) → Bi + SnO3^(2-) (basic solution)
--- I separated the equation into two and i know the next step is to balance the e-... i just don't know how to?
6H + Bi(OH)3 → Bi + 3H2O
H20 + SnO2^(2-) → SnO3^(2-) + 2H

We all take the same Chemistry class, we are not using different names. We've been using my computer and that's why. You can ignore whatever post you want, it's just sad that I relied on this website for help. To be mad because we supposedly change screen names is something very low of you. What's next, are you going to come at me if my name is not really Lucy or my classmate's name is not John or Addam. If this is a part time job for you then do your job right and stick to answering questions, don't do the questioning yourself.
