What is the minimum (least negative) cathode potential (versus she) needed to electroplate silver onto cutlery in a solution of ag+ and nh3 in which most of the silver ions are present as the complex ag(nh3)2+, and the concentration of ag+(aq) is only 3.15×10-5 m? (the reduction potential of ag+ vs. she is 0.7996 v.

yes it is balanced

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.

if it's not useful, feel free to report for mistake in answer.
