Rules for evaluation and completion of the course

Attendance is obligatory and may be checked. Studying is checked by periodical written tests on seminars and active learning activities.
Seminar:
Average of results of periodical written tests (50 points at least); when lower than 50 summary test should be written and 50 points achieved at least.
Exam:
Combination of avergae from seminars (weight 30%) and results of exam (weight 70%). The exam has written and oral part. Written part - ten questions, answers marked by up to 10 points, limit to pass and for oral exam: 50 points. Failed oral part may be repeated without repeating written part.
Attendance is obligatory and may be checked. Studying is checked by periodical written tests on seminars and active learning activities.

Aims

Finishing this course students will be able to describe and explain behavior of chemically reacting as well as non-reacting (multiphase) systems using the quantities, principles and equations of thermodynamics and to explain behavior and properties of aqueous solutions of electrolytes and how to explore their ability to conduct electrical current
