Three standard reduction electrode potentials are given as E(A)=-1.00 V for A+(aq)/A(s); E(B)= -0.50 V for B+(aq)/B(s); and E(c)=-0.25V for C+(aq)/C(s). Which of the following chemical reactionswill spontaneously occur? Briefly explain.

(a) A(s) + B(s)A+(aq) + B+(aq)

(b) A+(aq) + B+(aq)A(s) + B(s)

(c) A(s) + B+(s)A+(s) + B(s)

(d) C(s) + B+(aq)C+(aq) + B(s)

(e) A(s) + C+(aq)A+(aq) + C(s)

(f) A+(aq) + C(s)A(s) + C+(aq)

A certain half-reaction has a standard reduction potential E0red=+0.99V. An engineer proposes using this half-reaction at the cathode of a galvanic cell that must provide at least 1.30V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the cathode of the cell.

Calculate the cell voltage under these conditions. Round your answer to 

Balance the following redox reaction in basic solution.
