Learning objectives
The aim of the teaching is to provide a knowledge of basic chemistry, preparatory to the subsequent teachings of Organic Chemistry and Biological Chemistry. More specifically, the teaching will provide the minimum tools necessary for understanding the chemical language and basic topics (atoms, chemical bonds, chemical reactions, chemical, thermodynamic and electrochemical equilibrium). This basic knowledge constitutes the necessary tools for understanding the chemical language of life, an indispensable element for the future biological studies.
Expected learning outcomes
At the end of the teaching, the student will have to reach skills relating to the structure of matter and chemical bonds. The concepts learned will guide the graduate to work competently in all phases of the experimental and analytical management of chemical processes. In particular, the basic concepts of nomenclature, chemical formulas and stoichiometry, and the concepts concerning solutions, dissociations in solution, chemical and electrochemical equilibria, pH and buffer solutions must be applied.

Lesson period
First semester
Due to the SARS-CoV2 emergency in 2019-2020, the course will be held remotely (in synchronous and asynchronous mode) in the first half of the AY 2020-2021. Lectures (40 hours) will be recorded on the Personal Computer of the teacher. The videos will be made available through the ARIEL platform and/or "Microsoft Teams" platform. Some activities and exercises (16 hours) will be carried out in synchronous mode on the University's "Microsoft Teams". The same platform and other utility of Office365 will be used to interact with the students by assigning activities. The teacher will get in touch with students by e-mail, by the forum space available in the ARIEL platform or by using various communication tools.

Assessment methods and Criteria
The exam is written and divided into three parts: Part A (stoichiometric problems), Part B (questions) and Test. To pass the exam, it is needed to obtain the sufficiency separately in all parts (18 over 30 in part A/ B and in the test). Exercises are of the same type as the ones solved in class and taken from the coursebook.
