      Welcome to the General Chemistry 2 course, a part of the Pre-Health Sciences Training Certificate series. This course and certificate have been developed to cater to the needs of learners who are keen on gaining admission to health-related programs and who wish to fulfill the prerequisites for the Medical College Admission Test (MCAT).

      Our General Chemistry 2 course serves as an extension of the General Chemistry 1 course and offers learners a more comprehensive understanding of the foundational principles of chemistry. Through this course, learners will be able to delve deeper into the various topics covered in Module 1, providing a more expansive overview of the subject matter.

      The General Chemistry 2 course is sponsored in part by the International Development Research Centre and the University of the Incarnate Word School of Osteopathic Medicine. Like all NextGenU.org courses, it is competency-based, using competencies based on the Association of American Medical Colleges’ Medical College Admission Test.  It uses learning resources from accredited, academic, professional, and world-class organizations and universities such as Rice University. The course was designed by Alixandria Ali, BSc; Pablo Baldiviezo MD, MSc, DiplEd; Sherian Bachan MSc, BSc; Carolina Bustillos MD, DiplEd; Kabiru Gulma B. Pharm, MBA, MSc., Ph.D.; Felix Emeka Anyiam, MPH, MScPH, DataSc.; Marco Aurelio Hernandez Ph.D., MSc, MSc, BSc; Reisha Narine MSc, BSc; Sara Wildman, BSc; and Aduke Williams BA.

            • Temperature at the end of reaction = 28°C
            • Heat of fusion of KCl = 4.17 kJ/mol
            • Heat of reaction = -36.8 kJ
            • Entropy change of reaction = -21.2 J/K
            • Free energy of reaction = -30.2 kJ
