CP Chemistry Semester Two Exam
1. Students can prepare a both sides of a 3” X 5” HAND WRITTEN note card (no Xeroxed cards will
be allowed), which will be collected when exam is finished, please include your NAME.
2. Student should bring their own calculator to the exam. All calculators will have the memory erased
prior to the exam, and again after the exam is finished.
3. Teacher will provide a periodic table, polyatomic ion table and molecular shape and polarity sheet.
4. The exam will be composed of 70 multiple choice questions worth 140 points.
5. No equations, constants, conversions will be given on the exam. That information should be
included on the note card.
6. The student must decide what information to include on the note card.
7. Below is a list of topics for the exam. The student should go through each topic and write down any
needed information.
Topics may include:
Bonding and Naming
Ionic bond/ Metal & Nonmetal/ Cation & Anion Charges/ Electrostatic attraction/
Naming Ionic Compounds / Roman Numerals / Polyatomic Ions
Covalent Bond/ Nonmetal + Non Metal/ naming Molecular Compounds
Electronegativity difference to determine Nonpolar covalent bond/Polar covalent bond
Valence electrons – outermost S & P electrons
Stable Octet
Single bond /Double bond/Triple bond
Electron dot structures/Shared electron pairs/Unshared electron pairs
Valence Shell Electron Pair Repulsion Theory (VSEPR)
Predicting shapes - Tetrahedral / trigonal pyramidal/ trigonal planar/ bent / linear
Reactions
energy change-endothermic/exothermic
atom rearrangement
precipitate/precipitation
solute/solvent
Writing reactions
conservation of atoms
conservation of mass
balancing equations

diatomic elements
subscripts/parentheses/coefficients
symbols used in equations (g, l , s , aq ), ,  , etc.
Reaction types
combustion
synthesis
decomposition
single displacement (check activity series table)
double displacement (check solubility table)
CxHy + O2  CO2 + H2O
A + B  AB
AB  A + B
AB + C  CB + A or XY + Z  XZ + Y
AB + CD  AD + CB

mol
Ratios - mole ratios, molar mass, coefficient ratios
Reactants – excess/ limiting
Yield – actual/theoretical x 100 = % yield (how well a reaction proceeds)
Be able to:
determine the mass or moles of a product from the mass or moles of a reactant
determine the mass of a product from the limiting reactant
% yield from the theoretical yield and the actual yield
actual yield from the theoretical yield and the % yield
determine the mass or moles from volume of the reactant or product at STP
Gases
Properties of gases
Avogadro’s Law (22.4 L / mol) - a direct relationship of volume to number of moles(n) at STP
Standard Temperature and Pressure (STP) 0oC (or 273K) & 1 atm (= 760 mmHg or torr = 101.3 kPa = 14.7psi )
Convert pressures (atm to kPa to mmHg & torr) and temperatures (oC to K)
Relationship of pressure to volume  pressure =  volume
Relationship of pressure to temperature -  pressure =  temp
Relationship of volume to temperature -  volume =  temp

FINAL EXAM TIPS
Keep these tips in mind when preparing for final exams.


Begin studying 10 days to a week before finals to avoid ineffective cramming at the last minute.
Rather than reviewing the material chapter by chapter, make a list of general topics that are certain to be covered. Review
well-known concepts quickly; spend more time on problem areas.
If you choose to listen to music while studying, choose something light that is not distracting.
Take brief breaks as a reward for completing different sections of material. Avoid allowing the breaks to become longer than
the time spent studying. Instead of a break, use candy or a snack as an incentive.
After a week of preparation, relax the night before the final. Review a little, then watch television or read a good book.
Eat a good breakfast the day of the test to improve concentration and provide fuel for the brain.
RELAX. The more tense you are, the harder it will be to remember the material.
