You are conducting the Air Bag Lab with a ziplock bag that holds 500mL, how many moles of gas would be needed to fill the bag? 0.02mol 0.2mol 0.22mol 2.00mol

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's c (engineer's do their work with mechanical stuff not on any living being)
