LECTURE

MATERIAL

• Chapter 1: Be able to use Scientific Notation with ease, and handle all unit conversions - including metric prefixes, English to metric, and complex units (like speed and density).
  • Chapter 1   # 55, 57, 59-61, 71, 91, 97, 99, 124, 127
• Chapter 2:  You should be able to count subatomic particles (protons, neutrons, and electrons) for any atom, isotope, or ion.  You should be able to use a molar mass to convert between grams and moles, and use Avogadro's number.
  • Chapter 2 # 57, 61, 81, 85, 105
• Chapter 3: You should be able to handle basic naming of ionic and covalent compounds.  (I DON'T expect you to name acids, or the older names of transition metal ions like "stannic" or "mercurous.")  You should be fluent in polyatomic ions (Table 3.5, pg. 91): know their names, formulas, and charges!  Be able to use a molecular formula to convert from mass to moles of the entire molecule (molar mass) or from moles of a molecule to moles of an atom or ion within the compound (Pg 113).
  • Chapter 3  # 23, 37, 41, 43, 44, 47, 49, 59, 61
• Chapter 4:  Be able to predict the products of an acid base neutralization reaction. Understand what an electrolyte is and what it does when in an aqueous solution. You must understand Molarity, how to use it to convert between moles and liters of solution.  Although we won't do a ton of hard stoichiometry problems in Chem 2, you need a good understanding of how reactions work on a mole to mole (or molecule to molecule) basis and how limiting reactants are determined.
  • Chapter 4: # 6, 7, 49, 55, 57, 65, 69
• Chapter 6: Use Hess's Law to determine a heat of reaction, draw a reaction diagram showing both endothermic and exothermic reactions,  Understand the definition of a standard state (pg 275), be able to write the reaction associated with a standard enthalpy of formation, and determine an enthalpy of reaction from standard enthalpies of formation.
  • Chapter 6:# 25, 57, 59, 77, 81, 85
• Chapter 8:  Write an electron configuration for all atoms and ions.  Know which electrons on an atom are considered valence and which are core electrons.  Use valence electrons to determine and explain why atoms gain or lose electrons.
  • Chapter 8: # 30, 31, 45, 51, 52, 65
• Chapter 9:  Be able to draw Lewis structures for binary covalent compounds and including expanded octets and polyatomic ions.  Be able to draw resonance structures, and understand what resonance means to the strength of bonds and a molecule's stability.  Understand bond polarity based on the electronegativities of the atoms.
  • Chapter 9: # 51, 55, 59, 60, 64, 73, 75
• Chapter 10: VSEPR Structures!  Know Table 10.1 well; know electron geometries, molecular geometries (shapes), and bond angles.  Be able to reasonably draw the shapes in 3D (pg 436).  Be able to determine if a molecule is polar or nonpolar.
  • Chapter 10: # 5, 7, 35, 37, 47-52, 89, 90
