Chapter 14, Energy Changes in Chemical Reactions comes from the FHSST (Free High School Science Texts) Chemistry textbook. FHSST is a project that aims to provide free science and mathematics textbooks for Grades 10 to 12 science learners. The project was initiated by young South African scientists, and now brings together scientists from around the world who are willing to contribute to the writing of the books. Below is a complete Table of Contents for this chapter.
