please answer the full question. 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...
What is the balanced chemical equation for the electrochemical cell reaction expressed using shorthand notation below? Al(s) | A13+(aq) || Ni2+(aq) | Ni(s) O 2 Al(s) + 3 Ni2+(aq) + 2 A13+(aq) + 3 Ni(s) 3 Al(s) + 2 Ni2+(aq) → 3 A13+(aq) + 2 Ni(s) O 2 Ni(s) + 3 A13+(aq) + 2 Ni2+(aq) + 3 Al(s) O 3 Ni(s) + 2 A13+(aq) → 3 Ni2+(aq) + 2 Al(s)

b. Write the cell notation for the following redox reaction. Here, Cu+ or CuNO3 is oxidized to Cu2+ or Cu(NO3)2in the oxidation half-cell. Since there is only aqueous species and there is no electrode (metal) in the oxidation half-cell, use platinum (Pt) as an inert electrode in the oxidation half-cell. 3CuNO3(aq) + Au(NO3)3(aq) ⟶ 3Cu(NO3)2(aq) + Au(s)
