What does hess’s law make it possible for you to do?

you can represent heats of fusion and solidification on a graph called a heating curve.

you can determine the heat of vaporization if you know the heat of condensation.

you can calculate the heat of reaction by using standard heats of formation.

you can add ∆h for two or more thermochemical reactions to get the final heat of reaction.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

it would be a gas formation

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
