Study Notes

Intermolecular Forces

Repulsion increases exponentially as the distance between molecules decreases.
Intramolecular forces hold atoms together within a molecule and are stronger than intermolecular forces.
Intermolecular attractions are weaker than covalent or ionic bonds.
Polar molecules, like chloroform and acetone, have dipole-dipole interactions.

States of Matter

Matter occupies space and has mass.
The ideal gas equation is PV = RT.
For one mole of gas, the product of pressure and volume is constant at a given temperature: PV = RT.
