This text has the necessary features to hook introductory students and keep them interested and successful in preparatory chemistry. This book carefully guides beginning students through the fundamental principals and calculations required for their subsequent success in either the general chemistry course or the short organic and biology chemistry course. Krimsley, while dedicated to conceptual understanding and skill building, presents a book that provides students with complete explanations on every point and helps them work through the material methodically, with many examples and hints. His approach aims to be cohesive and coherent. Krimsley introduces all topics through an example students are already familiar with; he continually reminds them of objectives, and provides many opportunities to practice and then check their answers.
