Could anyone please help me with a Chemistry Assessment task? 
1) A galvanic cell is represented as follows: Zn/Zn2+//Cu2+/Cu E = +1.11V
Predict the effect on the standard cell potential if:
a) the Cu2+ concentration increases
b) the Zn2+ concentration decreases
c) the anode is increased in mass
d) a larger Zinc anode is used
e) the Zinc anode is powdered
AND
2) Americium-241 is used in home smoke detectors. It is an alpha emitter and has a half life of 458 years.
a) Smoke detectors often last only a few years before they have to be replaced. Suggest a reason why they fail.
