Can someone please tell me if I did the equations right and if the
anode and cathode reactions are correct .Homework Answers
First of all in each of the reaction the element which is going in the solution should with labeled with (aq) notation and your 2-5 reactions are the other way around, in each of these reactions the element in the anode is the cathode and would be going fron (aq) to (s) and the elements in the cathode should be in anode and going from (s) to (aq).
**(s) => solid
**(aq) => aqueous
here is the electrochemical potential series.

2. You measured cell potentials (voltages) for reactions of metals and metal ions. We will use the standard date and practice calculating these. Recall: E-Ecathode - Eanode Remember reduction occurs at the cathode; oxidation occurs at the anode For the anode reactions, your reactant will be on the product side of the standard equation, but don't change any sign. The equation does that for you. Cathode Reaction Agt + e → Ag Ecathode Anode Reaction...
