Chemistry by Paul Flowers, Klaus Theopold, Richard Langley, and William R. Robinson
Chemistry is designed to meet the scope and sequence requirements of the two-semester general chemistry course. The textbook provides an important opportunity for students to learn the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The book also includes a number of innovative features, including interactive exercises and real-world applications, designed to enhance student learning. (Source: OpenStax)
Biochemistry
Carnegie Mellon University Open Learning Initiative
This is an introductory course in biochemistry, designed for both biology and chemical engineering majors. A consistent theme in this course is the development of a quantitative understanding of the interactions of biological molecules from a structural, thermodynamic, and molecular dynamic point of view.
CHEM101: General Chemistry I
Saylor Academy
This course provides a detailed introduction to the basic principles and methods of chemistry, which are the foundation to all subsequent chemistry courses. It surveys the metric system, scientific notation and significant figures, the atom and atomic theories, trends of the periodic table of the elements, bonding, molecular geometry, chemical formulas, stoichiometry, gas laws, thermochemistry, and thermodynamics.
Chemistry for Majors
Lumen / Candela
