AP Chemistry

Chemistry

Grade 8-12

AP Chemistry is an Advanced Placement course and exam offered by the College Board. It is designed to provide high school students with a college-level understanding of chemistry and is typically taken by students who have completed introductory chemistry courses.

Course Overview:

AP Chemistry covers fundamental topics in chemistry, including atomic structure, chemical bonding, reactions, kinetics, thermodynamics, and equilibrium.

The course emphasizes problem-solving, laboratory skills, and critical thinking.

Key Concepts:

Atomic structure and periodicity
Chemical bonding and molecular geometry
Stoichiometry and chemical reactions
Kinetics and reaction rates

Exam Details:

The AP Chemistry exam assesses students' understanding of chemistry concepts, their ability to apply chemical principles, and their laboratory skills.

It consists of two main sections: multiple-choice questions and free-response questions.
The multiple-choice section contains around 60 questions.
The free-response section includes seven questions, including three long free-response questions and four short-answer questions.
