Teaching methods

The course is based on class lectures through slides, exercises and problems sessions. Tutorial activities are also provided mainly to help students in problem solving. Course's slides will be available to students.

Assessment methods

Upon successful completion of the course, students should: know and correctly use the language of chemistry, to understand the atomic and molecular nature of matter, to develop an ability to solve basic quantitative problems regarding chemical reactions, chemical equilibria, and chemical kinetics, understand and be able to apply chemical facts, concepts, and models, and be able to use them as a foundation to organize further chemical knowledge and to understand the physical world. Assessment method: written test and oral interview.

Teaching tools

All slides and other educational materials will be distributed in electronic format (http://campus.unibo.it/) and will be also available as hardcopies at the Copy Center near to library.

Moreover, a website to support student's activity will be regularly updated with the lecture schedule along with all the information concerning the course and the examinations. http://www.unibo.it/docenti/maurizio.toselli
