Advanced Placement Chemistry (AP Chemistry or AP Chem) is a course and examination offered by the College Board as a part of the Advanced Placement Program to give American and Canadian high school students the opportunity to demonstrate their abilities and earn college-level credit.The new exam has a focus on longer, more in depth, lab-based questions.The penalty for incorrect answers on the multiple choice section was also removed.Leaving Cert Chemistrynotes, sample answers, past exam papers, exam papers by topic, mcq revision tools, marking schemes and much more. Asked by: blindfire-ga, Answered by: bobbie7-ga 3 of 5 stars, , Answered. The boiling points of twelve organic compounds (from three chemical families). Hello, I humbly appreciate if you will answer these ff. The old test was composed of two sections: a multiple-choice section consisting of 75 questions with five answer choices each, and a free-response section consisting of six essay prompts that required the authoring of chemical equations, solution of problems, and development of thoughtful essays in response to hypothetical scenarios.While the use of calculators was prohibited during Section I and Section II Part B, a periodic table, a list of selected standard reduction potentials, and two pages of equations and conventions are available for use during the entirety of Section II.The College Board recommends successful completion of High School Chemistry and Algebra II; however, requirement of this may differ from school to school.AP Chemistry usually requires knowledge of Algebra II; however, some schools allow students to take Algebra II concurrently with this class.The course aims to prepare students to take the AP Chemistry exam toward the end of the academic year.AP Chemistry topics include atomic theory, chemical bonding, phases of matter, solutions, types of reactions, chemical equilibrium, reaction kinetics, electrochemistry, and thermodynamics.
