| Define Chemical Equlibrium (closed book) |
|
Definition
| The point at which both the forward and reverse reactions in a chemical equation have equal reaction rates. |
|
|
Term
| Define La Chatelier's Principle (closed book) |
|
Definition
| When a stress (such as change in concentration, pressure, or temperature) is applied to an equlibrium, the reaction will shift in a way that relieves the stress and restores equilibrium. |

Term
| Define oxidation number (closed book) |
|
Definition
| The charge that an atom in a molecule would develop if the most electronegative atoms in the molecule took the shared electrons from the less electronegative atoms. |
|
|
Term

Term
(closed book)
Be able to recognize if a substance is acidic or base by looking at their ph
Know the range of a:
stong acid
weak acid
neutral
weak base
strong base |
|
Definition
stong acid: ph of 0 - 1.9 ph
weak acid: ph of 2 - 6.9
neutral: ph of 7
weak base: ph of 7.1 - 12
strong base: ph 12.1 - 14 |
|
|
Term
(closed book)
Be able to order acids in terms of increasing ionization constants. |
|
Definition
The higher the pH, the weaker the acid. The weaker the acid, the smaller the ionization constant. Thus, high pH means low ionization constant. |
