At 25°C a zinc-copper battery is constructed as follows: Zn |Zn^2+ (0.1000 M)|| Cu^2+(2.500 M)|Cu

a. Calculate the cell potential (in units of volts) after 2.09 A of current has flowed for 5.34 h. Assume each half-cell contains 1.000 L of solution.
b. Calculate the cell potential after 10.0 A of current has flowed for 10.0 h. (Assume each half-cell contains 1.00 L of solution.)
c. Calculate the mass of each electrode after 10.0 h.
d. How long can this battery deliver a current of 10.0 A before it goes dead?

3 hours because it is a decent distance.

the answer is learned

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
