Unit 4: Chemical Reactions and Quantities
Test is on Thursday, February 16th
Chapter 7: The Mole
 The relationship between the mole, representative particles, mass, and volume
 Identify the representative particle of a specific substance (atom, molecule, formula unit)
 Identify how many of atoms of an element are in a representative particle of any substance
 Determine the molar mass of any substance
 Convert between mole, representative particle, mass, and volume
 Determine how much of an element is in a compound (percent composition and mass)
 Determine the empirical formula and the molecular formula of a substance given percent
composition or mass data
Suggested review problems from your textbook
Pg. 198 #45, 46, 47, 48, 49, 50, 55, 56, 57, 60, 61, 62, 63, 65, 66
Chapter 8: Chemical Reactions
 Write correct formula and word equations
 Balance equations
 Identify types of reactions
 Predict products and identify the states of matter depending on what type of reaction it is
 Use lab observations and flame tests to identify information about reactants and products
 Identify & explain whether or not single and double replacement reactions will occur
 Use solubility rules
Chapter 9: Stoichiometry
 Interpret balanced equations in terms of moles, representative particles, masses, and
volume of gases at STP
 Connect the relationship of substances to a balanced equation (mole ratio)
 Perform and interpret calculations between particles, mass, volume, and moles of two
substances involved in a reaction (stoichiometry map)
 Identify the limiting reagent (reactant) from data as well as lab observations
 Calculate the amount of excess reactant needed and how much will be left over
 Identify the amount of product produced based on limiting reagent (theoretical yield).
 Calculate % yield and identify possible sources of error from lab experiments
