Core Documentation

General chemistry theory lessons:
"Fondamenti di chimica" by Schiavello, Palmisano (6th edition) - EDISES
or : "Elementi di chimica generale" Petrucci Herring Madura Bissonnette - PICCIN
Can be replaced by any general chemistry textbook, as long as it is at the university level.

Students can use any college-level stoichiometry text.
Suggested:
"Esercizi di chimica generale" di Alessandro Del Zotto - EDISES
"Stechiometria per la chimica Generale" Lausarot Vaglio - PICCIN
"Capire gli esercizi di Chimica di base" - Cristina Della Pina - PICCIN

Type of delivery of the course

58 hours of theoretical lectures, 24 hours of numerical exercises concerning chemical calculations and solving stoichiometry problems.

Attendance

Not mandatory attendance.

Type of evaluation

The written exam consists of demonstrating knowledge of compound nomenclature and solving stoichiometry problems (duration 2.5-3 h). Passing the written test allows admission to the oral examination. The oral examination consists of a written test covering 4-5 topics from all course topics, followed by an oral interview.
