Chem 105 Fall ‘09 Dr. Ritchie
A Study Guide for the CHEM 105 Final Exam
Wednesday, 5/11/11; 8:00 AM; Brevard (Old Chemistry) 134
General Tips for Finals Week:
• Get a good night's rest – try to get at least 6 hours of sleep. Being well rested will do more
for your little gray cells that continuing to cram late into the night.
• For morning tests, make sure to set your alarm clock way, way before you go to bed.
(While you are at it, go ahead and set a second alarm clock in case you sleep through
the 1st one!)
• Eat a good breakfast – breakfast is the most important meal of the day. Marathon runners
know to eat complex carbohydrates (found in cereal and bread type foods) because they
will continue to provide energy longer than the simple carbohydrates in sugary foods.
Peanut butter is a great source of protein and brain powering fatty acids. Elvis loved PB
& Ba(Na)2 sandwiches! Now really, how can you question the King?
• Don't neglect your caffeine management – if you need caffeine to function, make sure to
bring your jumbo mug of java along with you.
• DON'T PANIC – Relax, stay calm, and work the problems. Don't be afraid to ask for help if
you don't understand something during the exam. You'll do awesome!
CHEM 105 Study Hints:
• The final exam will be cumulative
• Work all the homework problems!
• Make sure you know how to do all the problems on previous midterms and quizzes
(DISCLAIMER: This list is a review for the students that covers the general topics in the book
and is not necessarily a comprehensive review of all topics to be covered on the final)
Chapter 1: Matter, Measurement and Problem Solving—Phases of Matter, SI units,
Dimensional Analysis, Significant Figures
Know: how to convert between units and apply dimensional analysis to solve problems
Chapter 2: Atoms and Elements—Atomic Theory of Matter, Atomic Weights, Molecular and
Empirical Formulas, Ionic Compounds, Naming Inorganic Compounds
Know: how to calculate atomic masses and molecular formulas, how to predict ionic charges,
and how to name inorganic compounds
Chapter 3: Molecules, Compounds, and Chemical Equations—Chemical Equations, Patterns
of Chemical Reactivity, Formula Weights, The Mole, Empirical Formulas, Limiting
Reactants, Theoretical Yields
Know: how what stoichiometry of chemical equations mean, what a combustion reaction is, how
to calculate % composition from chemical formulas, how to convert between atoms and
moles (6.022x1023 atoms/mole), determine empirical formulas from combustion analysis,
figure out limiting reactants
Chapter 4: Chemical Quantities and Aqueous Reactions—Aqueous Solutions, Solubility and
Precipitation Reactions, Acids & Bases, Redox Reactions, Concentration of Solutions
Know: Strong and Weak electrolytes, solubilities and precipitation reactions, strong and weak
acids and bases (remember the 5 strong acids), neutralization reactions, oxidation and
reduction reactions (LEO says GER), determining concentrations, and dilutions
