answer 4 please
Laathode - Eanode Remember reduction occurs at the cath For the anode reactions, your rea Llculating these. per reduction occurs at the cathode: oxidation occurs at the anode actions, your reactant will be on the product side of the standard equation, but don't change any sign. The equation does that for you. say 1 Reaction Cathode Reaction Ecole Anode Reaction Ente Spontaneous | Cu+Ag Ag* + e → Ag .7996 Cu → Cu? + 2 . 34...

Given the half-cells: Ni/Ni+2 and Fe/Fe+2 Chose the anode and cathode. Calculate E° and ΔG° for this reaction. Calculate what the new cell potential (E) would be if the concentrations were [Ni+2] = 0.40 M and [Fe+2] = 0.30 M. Calculate how long you would have to run the battery at 6 amps to make the E drop by 0.03 volts, and calculate how many grams of anode you lose by that time. Using the equations: ΔG° = -nFE° ln...
