I have problem solving these problem

Which reaction would be most likely to occur at the anode of a voltaic cell? 2H2O(l)+2e- rightarrow H2(g)+2OH-(aq) 2H2O(l) rightarrow O2(g)+4H+(aq)+4e- 2H2O(l) rightarrow 2H2(g)+O2(g) PbSO4(s) rightarrow Pb2+(aq)+SO (aq) PbSO4(s)+2e- rightarrow Pb(s)+SO (aq) What is E of the following cell reaction at 25 degree C? E degree Cell = 0.460 V. Cu(s)|Cu2+(0.017 M)||Ag+(0.18 M)|Ag(s) 0.282 V 0.468 V 0.490 V 0.460 V 0.479 V What is the cell notation for the voltaic cell shown below? Zn(s)|Zn2+(aq)||Cu2+(aq)|Cu(s) Zn(s)|Cu(s)||Zn2+(aq)|Cu2+(aq) Zn2+(aq)|Zn(s)||Cu2+(aq)|Cu(s) Zn2+(aq)|Zn(s)||Cu(s)|Cu2+(aq) Zn(s)|Zn2+(aq)||Cu(s)|Cu2+(aq)
