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.
