Le Chatelier's Principle
If stress is applied to a system at equilibrium, the equilibrium will shift to relieve the stress.
Any atom surrounded by only two groups has this type of molecular shape and a bond angle of what?
Linear
180 degrees
Any atom that is surrounded by three groups has this molecular shape and these bond angles.
trigonal planar
120
Any atom surrounded by four groups has this molecular shape and these bond angles.
tetrahedral
109.5 degrees
If an atom is surrounded by four groups and one lone pair, what is the molecular shape and bond angles?
Trigonal pyramidal
<109.5
If there are four groups around an atom, and two of those groups are lone pairs, what is the molecular geometry and the bond angles?
Bent
<120
The law of conservation of energy
The total energy in a system does not change. Energy cannot be created or destroyed.
These two substances have concentrations that can vary; therefore, they can go into mass law expressions.
Aqueous solutions
Gases
The law of conservation of mass
In a chemical reaction, the mass of the products equals the mass of the reactants.
