Survey of Chemistry Practice Questions
Course
Introduction
Survey of Chemistry offers a broad introduction to the fundamental principles of chemistry, including atomic structure, chemical bonding, stoichiometry, states of matter, chemical reactions, and basic thermodynamics. Designed for students who do not require a rigorous, in-depth study of chemistry for their major, the course emphasizes conceptual understanding and practical applications of chemical principles in everyday life. Through a combination of lectures, demonstrations, and laboratory experiments, students gain insight into the role of chemistry in the natural world, technology, health, and the environment.
