Practice to Mastery: AP® Chemistry Workbook is a unit-by-unit practice book for students taking AP® Chemistry or a first college course in general chemistry. It holds 1,340 original questions, every one with a detailed explanation, organized into the nine units of the course framework and closed by a full-length practice examination.WHAT IS INSIDE9 units that follow the order of the AP® Chemistry Course and Exam Description, from atomic structure to electrochemistry1,270 multiple-choice questions: 1,210 in the units (150 each for the heavily weighted Units 3 and 8, 130 for every other unit) and 60 in the practice examination70 free-response questions: 7 per unit, including experimental-design and data-analysis questions and questions that connect two units, plus 7 in the practice examinationA full-length practice examination in the current format: 60 multiple-choice questions in 90 minutes and 7 free-response questions (3 long, 4 short) in 105 minutesReference pages with the constants, equations and atomic masses used throughout the bookEXPLANATIONS YOU CAN LEARN FROMChemistry is a quantitative subject, so every calculation is worked step by step, with units carried through each line and answers reported to the correct number of significant figures. Every conceptual answer sets out the full chemical reasoning: which particles, which interactions, and why. Each free-response question has a point-by-point scoring guide that shows what earns each point, which answers are acceptable, and the most common ways points are lost.BUILT FOR REAL PRACTICEEach unit begins with a list of the topics it covers. Part 1 holds the questions, multiple choice in order of difficulty and then free response with ruled space for written answers. Part 2 follows at once with the answer key, the explanations and the scoring guides, so each unit can be worked and checked in one sitting. Every unit question carries an [EASY], [MEDIUM] or [HARD] tag, so you can see whether a missed question points to a gap in the basics or to a need for more practice with harder material. The practice examination prints no tags, just like the real examination.The examination rewards students who can carry an idea from one unit into another, so many questions join units where the chemistry itself links them: stoichiometry through equilibrium, acid-base and electrochemical calculations; enthalpy through entropy and free energy; rates through equilibrium; and atomic structure through bonding, intermolecular forces and the properties of substances.WHO IT IS FORStudents taking AP® Chemistry who want steady practice alongside their courseStudents preparing for the examination who need targeted practice by unitSelf-studying students and students in a first-year college general chemistry courseTeachers looking for original practice material for classwork, homework and reviewThe book includes three study plans: working alongside the course, focused examination preparation, and self-study from the beginning.Every question, answer choice, data set, figure and explanation in this book is original. The companion volume, Practice to Mastery: AP® Chemistry Practice Exams, provides 12 more full-length practice exams.AP® and Advanced Placement® are registered trademarks of the College Board, which was not involved in the production of, and does not endorse, this product.
