Caiculate values for the galvanic cells based on the following overall reactions. Assume that all concentrations are 7.0 Mand that all partial pressures are 1.0atm. (This problem requires values in your textbook's specific appendices, which you can access through the oWlv2 Mindtap Reader. You should not use the OWlv2 References' Tables to answer this question as the values will not match.) a. Cr3+(aq)+Cl2(g)Cr2O72(aq)+Cl(aq) b. Ni2+(aq)+Ca(s)=Ca2+(aq)+Ni(s) e=V
