The ninth edition of CHEMISTRY, International Edition incorporates a strong molecular reasoning focus, amplified problem-solving exercises, and innovative technological resources. This kind of reasoning helps students think at the molecular level and make connections between molecular structure and macroscopic properties. Molecular reasoning and visualization are emphasized via Molecular-Reasoning icons, chapter objectives, chapter essays, and end-of-chapter problems, and are integrated into OWL (Online Web-based Learning) and interactive resources on the Student Companion Site.
