I think these I know how to do ....just want someone to check..still sorta mixed up on teh first question. Thanx

For the following reaction, what is the correctly balanced reduction half-reaction?
Fe(OH)3(s) + Cu(s) → Fe(s) + Cu+(aq) + OH-(aq)

A. e- + Fe(OH)3(s) → Fe(s) + OH-(aq)
B. 3 e- + Fe(OH)3(s) → Fe(s) + 3 OH-(aq)
C. Fe(OH)3(s) → Fe(s) + 3 OH-(aq) + 3 e-
D. Cu(s) → Cu+(aq) + e-
I think answer is C

For the following reaction, what is the correctly balanced overall reaction?
Fe(OH)3(s) + Cu(s) → Fe(s) + Cu+(aq) + OH-(aq)

A. Fe(OH)3(s) + Cu(s) → Fe(s) + Cu+(aq) + 3 OH-(aq)
B. Fe(OH)3(s) + 2 Cu(s) → Fe(s) + 2 Cu+(aq) + OH-(aq)
C. Fe(OH)3(s) + 3 Cu(s) → Fe(s) + 3 Cu+(aq) + 3 OH-(aq)
D. 3 Fe(OH)3(s) + Cu(s) → 3 Fe(s) + Cu+(aq) + 9 OH-(aq)

i thnk answer is A

if either is wrong can sum1 explain why? thanx
