Welcome to the Companion Website for General Chemistry! Students and professors can use this site as an aid to your chemistry course. Pick a chapter below and click Begin.
How Students Can Use This Website
The practice quizzes here provide instant feedback for your answers, helping you to understand quickly the right way to think about the problems. Use them as preparation for your homework assignments and exams. (Your professor might even assign these quizzes as your homework!) Use the 3D Molecule Center and the Student Tutorials module as a visual reinforcement for some of the geometric concepts explained in the book. Use the Web Resources module to do web-based research or homework for the topics in each chapter.
How Instructors Can Use This Website
Use the Syllabus Manager to distribute online and offline assignments. You can use the practice exercises and quizzes here as homework sets that will be automatically graded for you, and the results sent to you by email. For example, assign a Explorer Quiz set before starting a chapter in lecture to encourage students to do preparatory reading; the results of the automatic grading will also show you which topics students found difficult and need special emphasis in class. Use the Web Resources area to assign special web-based research questions. Use the 3D Molecule Center and the Student Tutorials projected in lecture to illustrate difficult or highly visual concepts.
