A 42.2 g sample of acetic acid is heated using 1043 cal. What is the change temperature of the acetic acid?

H=mc∆T

∆T = H/mc

You have the mass and Heat Energy applied

Get the specific Heat capacity of acetic acid

Plug it into the formula...You should get the answer you're looking for

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.

diaria maybe go see a doctor about that
