The overall equation for a certain electrochemical cell is given below: Pb(s) + Cu2+(aq) → Pb2+(aq) + Cu(s)
a. Assuming standard conditions, draw a fully labelled diagram of the electrochemical cell
b. Write the half equations at the anode and cathode and calculate the cell potential, V, of the electrochemical cell.

lol idk man i guess u gotta ask bill nye the science guy

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
