How do I do these questions? Thanks! Which half-reaction will take place at the cathode during the electrolysis of molten MgCl2? Cl2 + 2e- rightarrow 2Cl- 2 Cl- rightarrow Cl2 + 2e- Mg rightarrow Mg2+ + 2e- Mg2+ + 2e- rightarrow Mg Which half-rcaction will take place at the cathode during the electrolysis of 1.0 M AgNO3? 2H2O + 2e rightarrow H2 + 2OH- Ag+ + e- rightarrow Ag Ag rightarrow Ag+ + e- 2H2O rightarrow O2 + 4H+ + 4e- Which half-rcaction will take place at the anode during the electrolysis of 0.10 M aqueous KF solution? 2F- rightarrow F2 + 2e- 2H2O rightarrow O2 + 4H+ + 4e- K+ + e- rightarrow K 2H2O + 2e- rightarrow H2 + 2OH- Which half-rcaction will take place at the anode during the electrolysis of 1.0 M AgNO3? 2H2O rightarrow O2 + 4H+ + 4e- 2H2O + 2e- rightarrow H2 + 2OH- Ag+ + e- rightarrow Ag Ag rightarrow Ag+ + e-
