FeCl3(aq) and Na2SO4(aq) Express your answer as a net ionic equation. Identify all of the phases in your answer. Enter noreaction if no precipitate is formed.

Let's first write the chemical dissociation processes:

FeCl3(aq) = Fe3+(aq) + 3Cl-(aq)

NH4(NO)3(aq) = NH4+(aq) + 3NO3-(aq)

When solutions are mixed no precipitate formed, due to the solubility of all the reaction products. So there's no chemical reaction between them, because Fe(NO3)3 and NH4Cl are soluble.

Explanation:

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.
