Learning outcomes
After completing the course, the student will have acquired the physical and mathematical bases to understand structure and properties of matter and the physical and chemical transformations concerning atoms and molecules in their aggregation states.
The laws of thermodynamics, dealing with energy transformations, and the fundamentals of kinetics , investigating the speed of chemical reactions and the factors influencing them, will be presented.
Finally, the course will deal with the principles of quantum mechanics and their applications consistently explaining the properties of atoms and molecules, the nature of the chemical bond, and the spectroscopic properties. Theoretical topics will be supplemented by examples, numerical exercises and practical laboratory tests.

Assessment methods
Assessment for Course 67037
After each lab practical, the students in each group must draft a summary report, using the template provided, in which only the experimental data must be reported and commented on. The summary reports must be submitted by the next laboratory session, or— for the final practical—within 8 days of its conclusion.
At least 24 hours before the final exam, a single detailed individual report on one of the lab experiments (freely chosen by the student) must be submitted by email in digital format (Word or PDF). This report must be written according to the instructions provided during the laboratory course lectures.
The mark for course 67037 comprises:
-
the overall evaluation of the group summary reports (maximum 5/30), and
-
the individual detailed report (maximum 5/30),
for a total maximum of 10/30, to be added to the mark obtained in course 67035.
Please note: the individual report must be submitted before the final exam. If the deadline is missed, the evaluation for course 67037 will be based only on the summary reports.
Students with learning disorders and\or temporary or permanent disabilities: please, contact the office responsible (https://site.unibo.it/studenti-con-disabilita-e-dsa/en/for-students ) as soon as possible so that they can propose acceptable adjustments. The request for adaptation must be submitted in advance (15 days before the exam date) to the lecturer, who will assess the appropriateness of the adjustments, taking into account the teaching objectives.
