voltaic cell is constructed from a standard Mn2+|Mn half cell (E° red = -1.180V) and a standard Ag+|Ag  half cell (E° red = 0.799V).       (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is:     +              +     The cathode reaction is:     +              +     The spontaneous cell reaction is:     +              +     The cell voltage is ___ V.

Consider the galvanic cell based on the following half-reactions: Zn+ + 2e + Zn e° = -0.76 V Cd²+ + 2e → Cd e° = -0.40 V a. Determine the overall cell reaction and calculate e (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (5). If a box is not needed, leave it blank.) b. Calculate AG° and K for the cell reaction at 25°C. AG kJ K = [Zn**] = 0.10 M and [Ca] = c. Calculate e cell at 25°C when Zn 1.2 x 10-5 M. Ecell =

A voltaic cell is constructed in which the anode is a Pb|Pb2+ half cell and the cathode is a I-|I2 half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is:     +              +     The cathode reaction is:     +              +     The net cell reaction is:     +              +     In the external circuit, electrons migrate _(from or to?)__ the I-|I2 electrode _(from or to?)__the  Pb|Pb2+ electrode.In the salt bridge, anions migrate _(from or to?)__ the Pb|Pb2+ compartment _(from or to?)__ the I-|I2 compartment.
