CHEM 123 Practice Problems Work (and learn) from your text book and stay ahead of your instructor throughout the term. This will help you get the most out of the lectures. By working ahead, you can identify topics you find difficult before they come up in lectures. (See if your instructor’s discussion helps you understand these difficult concepts. If not, ask for clarification during lectures.) The week-by-week schedule outlined on the next few pages encourages you to build your problem-solving skills gradually. When working through the problems, write down all steps as if you were going to hand in your solutions for marking. A clear, organized approach will help you think through a problem. Hints to help you with the Part b problems are available on UW-ACE. Note: CHEM 123 is the continuation of CHEM 120. There are a number of concepts from CHEM 120 which you must know (and should review, if necessary). These include: SI base units and SI prefixes; reaction and solution stoichiometry (e.g. mass- to-moles conversions, molarity calculations, using the ideal gas equation and partial pressures); thermochemistry and Hess’ Law; basic organization of the periodic table and periodic trends; drawing Lewis structures and predicting molecular geometry; assigning formal charges ( always show non-zero formal charges in any structure you draw! ); bonding concepts (e.g. ionic vs. covalent bonding, polar covalent bonds, electronegativity); oxidation-reduction (redox) concepts (e.g. oxidation numbers, balancing redox reactions) Textbook Exercises: Many of the end-of-chapter exercises from the text emphasize concepts from specific sections. Use these exercises, together with the self-assessment exercises, to help you decide if you are ready to move on to the next section or chapter or if you should spend more time working with concepts in the current section or chapter. The Integrative and Advanced Exercises are multi-concept problems that integrate material from different sections or earlier chapters. Use these exercises to help assess your ability to connect and integrate important concepts. Extra Problems: These problems are numbered B1 through B33 and are given on pages 7 to 9 of this booklet. Use them to gain additional practice working with concepts many students find challenging.
