Please please help me with this problem!!!!?

Question

Consider the following half-reactions and E0 values:

Ag+(aq) + e- --> Ag(s) E0 = 0.80 V
Cu2+(aq) + 2 e- --> Cu(s) E0 = 0.34 V
Pb2+(aq) + 2 e- --> E0 = -0.13 V

a/ Which of these metals or ions is the strongest oxidizing agent? Which is the strongest reducing agent?

b/ The half-reaction can be used to construct three different galvanic cells. Tell which cell delivers the higest voltage.

c/ Write the cell reaction for par (b) and calculate the values of E0, ΔG0 (in kilojoules), and K for this reaction.

d/ Calculate the voltage for the cell in part (b) if both ion concentration are 0.010M

Answer 1

I'll start you on your way.
Ag+ is the strongest oxidising agent, because it has the most positive E value. Pb metal is the strongest reducing agent because it has the most negative E value.
So combining those two into a cell will give the largest voltage difference.
The equation will be Pb + 2Ag+ ---> 2Ag + Pb2+

Now you can do the calculations.

Answer 2

He could try a various style of shaving gel, a number of them are designed to help soften up the stubble. for sure it is many times for the shave itself. over the years i could think of your epidermis will become used to the abrasive nature of his chin. A lotion on your epidermis earlier making out could help additionally. perchance he could desire to enhance a goatee or a beard. long facial hair does tend to be softer.
