Fundamentals of Chemistry Exam Bank
Course Introduction
Fundamentals of Chemistry introduces students to the basic principles that govern chemical interactions and reactions. The course covers atomic and molecular structure, periodic properties, chemical bonding, stoichiometry, states of matter, solutions, acids and bases, and thermochemistry. Emphasizing both conceptual understanding and quantitative problem-solving skills, students will explore the foundational concepts necessary for further studies in chemistry and related scientific fields. Laboratory activities and demonstrations may be incorporated to reinforce theoretical knowledge through hands-on experience.
