Chapter 7: A correctly balanced chemical equation is at the foundation of any successful solution to stoichiometry problems in chemistry. Students are also introduced to the activity series of elements to allow them to predict whether or not a chemical reaction actually occurs. A video clip is used showing the decomposition of hydrogen peroxide into water and oxygen gas in the presence of a catalyst. This product uses the interactive capabilities of a computer. The chapter has an embedded end-of-chapter quiz, uses graphics, animations, user interactivity or embedded video on almost all pages. This product is designed to provide bite-sized pieces of information in an effort to enhance the scientific literacy of our next generation, not to overwhelm them with sheer quantity of information. Chapter 7 section titles: Writing a Chemical Equation • Composition Reactions • Decomposition Reactions • Replacement Reactions • Replacement Reactions • Review and Practice • Chemical Equilibrium • Rate • Reactions Quiz. This product works both on a Macintosh or PC computer.
