Question 1

Using the following portion of the activity series for oxidation half-reactions, determine which combination of reactants will result in a reaction.

Li(s) → Al3+(aq) + e-
Cr(s) → Al3+(aq) + 3e-

◦ Li+(aq) with Al(s)
◦ Li(s) with Al(s)
◦ Li(s) with Al3+(aq)
◦ Li+(aq) with Al3+(aq)

Question 2

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

K(s) → K+(aq) + e-
Al(s) → Al3+(aq) + 3e-
Fe(s) → Fe2+(aq) + 2e-
Sn(s) → Sn2+(aq) + 2e-

determine which reaction will occur.
◦ K+(aq) with Fe2+(aq)
◦ Al(s) with Sn(s)
◦ Al3+(aq) with Fe(s)
◦ K(s) with Sn2+(aq)
