AP chemistry: how to balance an oxidation-reduction reaction

AP Chemistry: how oxidation-reduction reactions involve the transfer of electrons between substances

AP Chemistry: how oxidation numbers change based on oxidation reduction reactions

AP Chemistry: stoichiometric calculations--how to find the amounts of products or reactants when the coefficients are different

AP Chemistry: how to use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction.

AP Chemistry: how to calculate the molarity of a solution prepared by dissolving a solid in water

AP Chemistry: examines the extent to which a solution can conduct electricity depends on the nuber of ions in the solution

AP Chemistry: electrolysis refers to the decomposition of a substance by an electric current

AP Chemistry: Nernst Equation relates the effective concentrations of the components of a cell reaction to the standard cell potential.

AP Chemistry: Le Chatlier's principle shows that differing concentrations will change equilibrium positions, which can affect cell potential

AP Chemistry: a cell can accomplish work through the transfer of electrons. Looks at the free energy released from a spontaneous reaction.

AP Chemistry: introduction to galvanic cells -- electric cells that generate an electromotive force by the conversion of chemical energy to electrical energy

AP Chemistry: standard reduction potential (EO) is a measure of the potential of a half-reaction reduced at standard conditions, measured in volts

AP Chemistry: in the study of thermodynamics, equilibrium implies not only the lack of change but also refers to the absence of any tendency toward change

AP Chemistry: the change in Gibbs free energy associated with a chemical reaction indicates whether or not the reaction will proceed spontaneously

AP Chemistry: Gibb’s free energy equation calculates the phase change temperature of a substance

AP Chemistry: during chemical reactions, the freedom of movement of the atoms often changes because of changes in the complexity of the molecules

AP Chemistry: the second law predicts the probability of dispersal of energy that is localized or concentrated in a group of molecules or atoms
