[ENagel]

Question 1

Using the following portion of the activity series for oxidation half reactions

Ca(s) → Ca2+(aq) + 2e-
Mg(s) → Mg2+(aq) + 2e-
Zn(s) → Zn2+(aq) + 2e-
Cu(s) → Cu2+(aq) + 2e-

determine which reaction will not occur.
◦ Zn(s) with Mg2+(aq)
◦ Zn(s) with Cu2+(aq)
◦ Ca(s) with Cu2+(aq)
◦ Ca(s) with Zn2+(aq)

Question 2

Using the following sequence of reactions, determine the order of reducing agents (strongest to weakest).

A + B+ → A+ + B
A + C+ → A+ + C
B + C+ → no reaction

◦ B > C > A
◦ A > C > B
◦ A > B > C
◦ C+ > B+ > A+
