Chemistry 103A Study Outline for Examination III June 25, 2003 Examination III will cover material from Chapters 6 (energy and chemical reactions), Chapter 7 (electron configurations and the periodic table), and part of Chapter 8 (covalent bonding). The exam will run for 55 minutes, and you will need a calculator. The emphasis will be on problem solving. Most questions will be similar to those in the problem sets, practice problems, the examples worked in lecture and in the text chapters. You may bring one 3x5 card with notes on it (both sides) to the exam. YOU MUST BRING YOUR STUDENT PHOTO ID TO THE EXAM! ______________________________________________________________________ ENERGY AND CHEMICAL REACTIONS Distinguish between the change in internal energy and the change in enthalpy for a system (section 6.4). Use thermochemical equations and derive thermostoichiometric factors from them (Sections 6.5 and 6.6). Use the fact that the standard enthalpy change for a reaction, ? H °, is proportional to the quantity of reactants consumed or products produced when the reaction occurs (Section 6.6). Understand the origin of the enthalpy change
