Electrochemistry help needed

Convert the following into balanced ionic equations, then devoid of spectator ions, then divide each into ionic redox equation into half equations

Stating the Oxidation half equation, reduction half equation and identifying reductant and oxidant.

I'll just give 1 question so someone can help explain it to me, then i'll do the others myself

Oh and, if anyone is good with drawing the galvonic cell, would be much appreciated

1) Cu (s) + 2FeCl (aq) -> CuCl (aq) + 2FeCl (aq)
3 2 2

And what we will probably learn tomorrow just so I can get a better understanding
- Find the OS(someone define it for me?) of:
a) sulfur in H2S, H2SO3, SO2, K2S, SO4^2-,HSO3-, Fe2(SO4)3
