In stoichiometry, what is the conversion factor called that comes from the balanced equation?
The mole ratio.
What law states matter cannot be created or destroyed?
The Law of Conservation of Mass.
Why do substances with stronger intermolecular forces usually have higher boiling points
Because more energy is needed to separate the molecules
