taught the preparatory chemistry course and organic chemistry He is the original author of Foundations of College Chemistry and his name has become synonymous with clarity, meticulous accuracy, and a step-by-step approach that students can follow Over the years, more than three million students have learned chemistry using a text by Morris Hein In addition to Foundations of College Chemistry, Twelfth Edition, he is co-author of Introduction to General, Organic, and Biochemistry, Eighth Edition, and Introduction to Organic and Biochemistry He is also co-author of Foundations of Chemistry in the Laboratory, Twelfth Edition, and Introduction to General, Organic and Biochemistry in the Laboratory, Eighth Edition Susan Arena earned a BS and MA in Chemistry at California State UniversityFullerton She has taught science and mathematics at all levels, including middle school, high school, community college, and university At the University of Illinois she developed a program for increasing the retention of minorities and women in science and engineering This program focused on using active learning and peer teaching to encourage students to excel in the sciences She has coordinated and led workshops and progrms for science teachers from elementary through college levels that encourage and support active learning and creative science teaching techniques For several years she was director of an Institute for Chemical Education (ICE) field center in Southern California Susan enjoys reading, knitting, traveling, classic cars, and gardening in her spare time when she is not playing with her grandchildren ix PC-2 PHOTO CREDITS Chapter 11 Page 213: James M Bell/Photo Researchers, Inc Page 220: iStockphoto Page 227: Tom Pantages Page 231: Courtesy IBM Almaden
