25 ml of 2M AgNO3 reacted with 40 ml of 3M of Na2CrO4 as the following equation. Calculate the mass of precipitate Ag2CrO4. (Ag2CrO4 = 331.7 g/mol) 2AgNO3(aq) + Na2CrO4(aq) ===> Ag2CrO4(s) + 2NaNO3(aq)

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.

the dissolution of polymer can be thermodynamically described in 2 steps.

i think that the answer is c
