Set up a cell that has a Mg electrode in a 1.0 M aqueous Mg2+ solution on the left side and a Cu electrode in a 1.0 M aqueous Cu2+ solution on the right side. Add the salt bridge. What are the half-reactions for the anode and cathode that are associated with this chemical reaction? Include physical states. anode half-reaction: cathode half-reaction:

Enter electrons as e-. Use smallest possible integer coefficients for ALL reactions. If a box is not needed, leave it blank. A voltaic cell is constructed in which the following cell reaction occurs. The half-cell compartments are connected by a salt bridge. Hg2+(aq) + Mn(s) ⟶ Hg(l) + Mn2+(aq) The anode reaction is: The cathode reaction is: In the external circuit, electrons migrate the Hg|Hg2+ electrode the Mn|Mn2+ electrode. In the salt bridge, anions migrate the Mn|Mn2+ compartment the Hg|Hg2+ compartment.

A voltaic cell is constructed in which the anode is a Mn|Mn2+ half-cell and the cathode is a Cu+|Cu2+ half-cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: Mn(s) → Mn2+(aq) + 2e- The cathode reaction is: Cu+(aq) + e- → Cu2+(aq) The net cell reaction is: Mn(s) + Cu+(aq) → Mn2+(aq) + Cu(s) In the external circuit, electrons migrate from the Mn|Mn2+ electrode to the Cu+|Cu2+ electrode. In the salt bridge, anions migrate from the Mn|Mn2+ compartment to the Cu+|Cu2+ compartment.
