FORMULAS AND TABLESEXCERPTAbout Research & Education AssociationResearch & Education Association (REA) is an organization of educators, scientists, and engineers specializing in various academic fields. Founded in 1959 with the purpose of disseminating the most recently developed scientific information to groups in industry, government, high schools, and universities, REA has since become a successful and highly respected publisher of study aids, test preps, handbooks, and reference works.
REA's Test Preparation series includes study guides for all academic levels in almost all disciplines. Research & Education Association publishes test preps for students who have not yet completed high school, as well as high school students preparing to enter college. Students from countries around the world seeking to attend college in the United States will find the assistance they need in REA's publications. For college students seeking advanced degrees, REA publishes test preps for many major graduate school admission examinations in a wide variety of disciplines, including engineering, law, and medicine. Students at every level, in every field, with every ambition can find what they are looking for among REA's publications.
While most test preparation books present practice tests that bear little resemblance to the actual exams, REA's series presents tests that accurately depict the official exams in both degree of difficulty and types of questions. REA's practice tests are always based upon the most recently administered exams, and include every type of question that can be expected on the actual exams.
REA's publications and educational materials are highly regarded and continually receive an unprecedented amount of praise from professionals, instructors, librarians, parents, and students. Our authors are as diverse as the fields represented in the books we publish. They are well-known in their respective disciplines and serve on the faculties of prestigious high schools, colleges, and universities throughout the United States and Canada.
PREFACEThis book provides an accurate and complete representation of the Advanced Placement Examination in Chemistry. Our six practice exams are based on the most recently administered Advanced Placement Chemistry Exams. Each exam is three hours in length and includes every type of question that can be expected on the actual exam. Following each exam is an answer key complete with detailed explanations designed to clarify and contextualize the material. By completing all six exams and studying the explanations which follow, you can discover your strengths and weaknesses and thereby become well prepared for the actual exam.
The formulas and tables for the AP Chemistry Exam can be found at the back of this book, beginning on page 417. You will be provided these formulas and tables when you take the actual exam. You should also use this material when taking the practice tests in this book.
ABOUT THE TESTThe Advanced Placement Chemistry Examination is offered each May at participating schools and multi-school centers throughout the world.
The Advanced Placement Program is designed to allow high school students to pursue college-level studies while attending high school. The participating colleges, in turn, grant credit and/or advanced placement to students who do well on the examinations.
The Advanced Placement Chemistry course is designed to be the equivalent of a college introductory chemistry course, often taken by chemistry majors in their first year of college. Since the test covers a broad range of topics, no student is expected to answer all of the questions correctly.
The exam is divided into two sections:
1) Multiple-choice: Composed of 75 multiple-choice questions designed to test your ability to recall and understand a broad range of chemical concepts and calculations. This section constitutes 45% of the final grade and you are allowed 90 minutes for this portion of the
exam. Calculators are not permitte
THE AP CHEMISTRY EXAM
ABOUT THE EXAMINATION
The Advanced Placement Chemistry Examination is offered each May at participating schools and testing centers throughout the world. The Advanced Placement Program is designed to allow high school students to pursue college-level studies while attending high school. Participating colleges, in turn, grant credit and/or advanced placement to students who do well on the examinations.
The Advanced Placement Chemistry course is designed to be the equivalent of a college introductory chemistry course, often taken by chemistry majors in their first year of college. Since the test covers a broad range of topics, no student is expected to answer all of the questions correctly. (Consequently, it is important for students to not feel defeated when confronting a question that appears unanswerable.)
The examination follows the outline, published by the College Board, that appears below. The exam is divided into two, 90 minute sections. The first section is composed of 75 multiple-choice questions designed to test recall of a broad range of concepts and calculations. The score students earn on the multiple-choice test composes 45% of the total score. Calculators are not permitted on the multiple choice portion of the exam, although simple arithmetic may be needed to answer some questions.
The second section is a free-response exam and constitutes 55% of the final grade. Calculators are allowed on Part A, during which the student has 40-minutes to complete two problems. Calculators are not allowed on Part B, during which students have 50 minutes to complete chemical reaction questions and three essay questions. Most hand-held calculators are allowed in the examination. However, calculators with typewriter-style (QWERTY) keypads are not allowed. If you are unsure if your calculator is permitted, check with your teachers or Educational Testing Services.
A detailed outline of the topics on the examination and specific strategies for both portions of the Advanced Placement Chemistry examination follow.
