* While this a very full list, it’s always possible that I’ve overlooked something when putting this together. I suggest that you carefully review your class notes, ALEKS topics, worksheets, and labs, and, of course, be sure you have read the chapters well. Chem 142A Summer 2011 - List of Topics to Review for Exam 2* We have started applying the concepts we learned in Chapters 1-4.8 to new reactions and experimental conditions. It is assumed for Exam 2 and future exams that you know ALL of the material on the Exam 1 topic list, regardless of whether or not it showed up on Exam 1. You can expect to see comprehensive problems on future exams, so please be sure that you keep those previous chapters in mind as you study, work through problems, and take the exam. Atoms, Molecules, and Ions (Chapter 2, section 9) Naming covalent and ionic compounds (know name to formula and formula to name, including acids) (49, 52-53, 62) Types of Chemical Reactions and Solution Stoichiometry (Chapter 4, sections 9-11) Acid-base (neutralization) reactions o Transfer of protons: acids as proton donors and bases as proton acceptors o Calculating molarity of H + (H 3 O + ) in a solution of acid o Recognize the strong acids and bases (so you know what’s going on in solution: full dissociation vs. partial dissociation) o Write the molecular, complete ionic, and net ionic equations to describe a reaction (9, 40-41) o Stoichiometry calculations involving acid-base reactions (same as in chapter 3 once you know what the products are and you have a balanced chemical equation; calculate the amount of base needed to neutralize a given amount of acid, or vice versa) (42-45, 47-48, 51, 53-54, 79, 83, 93) o Titrations: what are they and how/why are they used; definitions: titrant, buret, indicator, etc.; calculations for titration reactions (see the previous bullet point about “stoichiometry” calculations) (46, 49-50, 52, 88) Reduction-oxidation (REDOX) reactions o Transfer of electrons: oxidation (loss of electrons) for one substance is balanced by reduction (gain of electrons) of another; conservation of electrons (58) o Assigning oxidation numbers/states: know the rules for the atoms/ions that are always the same so that you can deduce the oxidation numbers for the other atoms/ions in a compound (55-57) o Based on changes in O.N./O.S., identify a reaction as being a redox reaction
