What is the Ideal Gas Law?
PV=nRT
Molar volume at STP?
22.4L
Combined gas law formula?
P₁V₁/n₁T₁ = P₂V₂/n₂T₂
Kinetic Molecular Theory assumption?
Gas particles have negligible volume and no attraction.
Formula for rate of diffusion?
Rate ∝ √(3RT/MM)
Differences in states of matter?
solid- particles tightly packed (no translational movement)
liquid- particles tightly packed (constant translational movement)
gas- particles spread apart and move
Types of intermolecular forces (IMFs)?
London dispersion forces
dipole-dipole
hydrogen bonding
ion dipole interaction
What affects boiling/melting points?
Strength of IMFs
