The dipole of a molecule is determined by the

electronegativity of the elements.

Stoichiometry uses the

mole to mole ration for chemical equation

Polar molecules have intermolecular attraction where the + area of a molecule

attracts to the - area of another molecule.

In order for a compound to change from a liquid to a gas, enough energy

must be added to break the intermolecular attraction.

The gray shading is electron density, what does this tell us about the 2 atoms?

B has a higher electronegativity than A.

an arrow pointing to the most En elements in a molecule.

A hydrogen bond is a type of dipole interaction between a hydrogen atom bonded to

atoms such as nitrogen, oxygen, or fluorine.

These molecule is aligned in the electric field in a way that has

the + side of the molecule closest to the negative plate.

the product and sum of the elements mass in a compound.

uneven distribution of electrons in a bond.

In order to use stoichiometry

you must have a balanced chemical equation.

If a substance is polar it has a higher melting and boiling point because

it takes more energy to separate the molecules.

High melting and vaporization temperature mean

a compound has strong intermolecular forces.

have uneven sharing of electrons.

electronegativity increase (tricky)

L to R in a period and up a group

When a liquid is heated why does it begin to change from a liquid to a gas?

The intermolecular forces of attraction are weakened.
