Using data found in Appendix E of your textbook calculate the nonstandard emf for each of the following reactions if the concentration of each of the ions in these reactions is 0.0007 molar and everything else is standard (use 298 K for the temperature, R = 8.314 J/mol-K, and F = 96,485 C/mol):
(a) 2 Li+(aq) + 1 Sn(s) --> 2 Li(s) + 1 Sn2+(aq)
(b) 1 Zn2+(aq) + 1 Ca(s) --> 1 Zn(s) + 1 Ca2+(aq)
(c) 1 Mg2+(aq) + 1 H2(g) --> 1 Mg(s) + 2 H+(aq)
(d) 2 Al3+(aq) + 3 Pb(s) --> 2 Al(s) + 3 Pb2+(aq)
