Chemistry Final Exam Study Guide Last Week

End of Year Survey

RF: Oxidation Reduction Test,
Half Life Intro Lab
25.1?

TW: Talk about final exam, review problems from sections in the book, answers and examples.
1.) Alpha, Beta, Gamma
2.) Fission vs. Fusion
3.) Half Life

RF: Final Exam
Approximately 1/3 of the Test will be over Nuclear Chemistry Chap. 25 (Alpha, Beta, Gamma, 1/2 life, Fission vs. Fusion)

Approximately 2/3 will be Cumulative on the following Topics...
Oxidation vs. Reduction

Types of Reactions: Combination, Decomposition, Combustion, Acid-Base, Single Replacment, Double Displacement.

Balancing Reactionshttp://www.blogger.com/post-edit.g?blogID=662225748061296657&postID=3273519129897741532

Thermochemistry (First and Second Laws of Thermodynamics, heat=mass*temperature change*specific heat (when warming or cooling), heat=# moles* molar heat of fusion/vaporization)

Gas Laws (PV=nRT, P1V1=P2V2, P1/T1=P2/T2, V1/T1=V2/T2)

Acids and Bases (neutralization reactions, pH, H+ and OH-)

Precipitation Reactions

Stoichiometry Problems

Concentration (% Mass, % Volume, Molarity Calculations)

Periodic Table (Cations, Anions, Octet Rule-how many electrons lost/gained to become stable)
