Prentice Hall Chemistry meets the needs of students with a range of abilities, diversities, and learning styles by providing real-world connections to chemical concepts and processes. The first nine chapters introduce students to the conceptual nature of chemistry before they encounter the nore rigorous mathematical models and concepts in later chapters. The technology backbone of the program is the widely praised Interactive d104book with ChemASAP, which provides frequent opportunities to practice and reinforce key concepts with Animations, Simulaitons, Assessment, and Problem-solving tutorials.
