which arrow would most likely represent the phase change that occurs when silver is poured into a mold and cools to
become a solid bar?

b..

is the correct one

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

the answer is true.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
