KEY CONCEPTS:

Boyle's Law: Pressure and Volume inversely proportional when Temperature is constant

Charles's Law: Volume and Temperature directly proportional when Pressure is constant

Gay-Lussac's Law: Pressure and Temperature directly proportional when Volume is constant

Combined Gas Law: Combines ALL 3 equations into 1

NOTE: Initial terms on left of equal sign and final terms on the right

KEY CONCEPTS:

A=represents the CENTRAL ATOM
X=represents the number of surrounding atoms
E=represents the number of unshared electrons surrounding the CENTRAL ATOM
