Answer:
<u>Balanced equation:</u>

Explanation:
The chemical reaction between Lead(II) Nitrate and potassium carbonate is as follows.


<u>Ionic equation:</u>

Cancel the same ions on the both sides of the reaction.
The net ionic equation is as follows.

Answer:
Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)
Explanation:
In writing the cell notation for an electrochemical cell, the anode is written on the left hand side while the cathode is written on the right hand side. The two half cells are separated by two thick lines which represents the salt bridge.
For the cell discussed in the question; the Mn(s)/Mn^2+(aq) is the anode while the Co^2+(aq)/Co(s) half cell is the cathode.
Hence I can write; Mn(s)/Mn^2+(aq)//Co^2+(aq)/Co(s)
