[answerhappygod]

* an Al(s) electrode in 1.0M Al(NO3)3 solution
* a Pb(s) electrode in 1.0M Pb(NO3)2 solution
a. write a half reaction for the first half cell (Al/Al(NO3)3). What is E0cell?
b. write a half reaction for the second half cell (Pb/Pb(NO3)2). what is E0cell?
c. write the combined cell reaction. (aka redox rxn)
d. identify oxidizing & reducing agents
e. Pick (Al/Al(NO3)3) to be the anode and (Pb/Pb(NO3)2) as the cathode. What is the E0cell?
f. What does the sign of E0cell convey?
g. Now reverse the half cells, what does the sign of E0cell convey?
h. Which arrangement gives "useful work"? How can you tell?
i. Write out a line diagram for above.
j. sketch the entire cell
k. which electrode gains mass & which electrode loses mass?
