Chemistry for NCEA Level 3 contains full up-to-date coverage of NCEA Chemistry 3.1, 3.2, 3.3, 3.4, 3.5, 36 and 3.7. The achievement standards are presented in a logical teaching order, so that one standard leads onto the next. AS 3.4 describes particles and energy associated with their reactions. Often the energy appears as heat. Part of the energy can be transformed to electrical energy leading to AS 3.7, oxidation and reduction processes. Discussions of factors that determine whether a reaction will go are in both AS 3.4 (changes in enthalpy and entropy) and 3.7 (in terms of EÂ¬Ã values). This leads to an understanding of equilibrium reactions in AS 3.6. Following this is a quantitative study of the reactions encountered so far in AS 3.1. Problems involve both volumetric and gravimetric analyses. The next section looks at how the reactions impact on our lives and the world around us in AS 3.3. Finally, organic chemistry studies compounds from living things as well as man-made materials designed to make our lives easier but more interesting and challenging. This is AS 3.5. Spectroscopic methods in AS 3.2 allow us to rapidly identify the structure of substances. Only three types are studied in the curriculum, but they can give us a complete picture of many organic compounds. Extensive exercises are available throughout for students to self-assess their understanding throughout the course. Some exercises have been designed so that students have plenty to work on during a teacher's absence.
