Enter an equation for the precipitation reaction that occurs (if any) when solutions of ammonium chloride and calcium nitrate are mixed. Express your answer as a chemical equation. Identify all of the phases in your answer. Enter no reaction if no precipitate is formed.

Can someone very kindly provide me with an answer?

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.
