Final Exam 40 % 120 minutes
FINAL EXAM : Covers all material after Exam I.
COURSE DESCRIPTION:
This course will cover the fundamental principles of chemistry such as atomic structure and
bonding, periodic properties which govern chemical reactions of elements. The course focuses
on mass relationship in chemical reactions and on reactions in solution mixtures. The basic
concepts of the properties of gases, chemical equilibrium, and thermochemistry will be also
covered.

At the end of this course, the student should be very confident of his knowledge about matter, it’s
structure and intrinsic properties. He will understand the key concepts of atomic and molecular
structure and the basics of chemical reactivity.

immediately to the instructor and a formal petition must be handed to the department. MAKE-UP
EXAMs will be conducted only under very strict circumstances (death, excusable illness) once
the petition from the science department has been accepted, otherwise a grade of ZERO will be
given to missing any of the exams.
EXAMS DATES:
The dates of exam I and II are set by the chemistry department and are included on the syllabus.
The exact time and location of the exams will be specified by the in department near the exam
date. No changes of these dates will be allowed for any reason.
