B. Which of the possible products is the precipitate, and how do you know?

it should be p1 v1 = p2 v2

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.

it is the most commonly accepted one

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
