Elements of Chemistry and Physical Chemistry
A.Y. 2020/2021
Learning objectives
The course aims to provide students with the basics of general chemistry and physical chemistry with the aim of preparing students to face the subsequent basic and characteristic s of the CdS.
Expected learning outcomes
At the end of the course the students will know the concepts of chemical element, atom and molecule and they will be able to use the Periodic Table of the Elements. Students will be able to carry out stoichiometric balances and apply the concept of chemical equivalence. Students will be able to manage the use of buffer solutions, solve redox reactions and perform calculations on the energy balance. At the end of the course the students will also be able to perform calculations to establish the reaction rates according to their order and temperature.

The lessons will be held on the Microsoft Teams platform and can be followed both synchronously on the basis of the timetable published on the University website and asynchronously because they will be recorded and left available to students on the same platform.
Sporadic face-to-face orientation meetings are also scheduled, if the regulations concerning social distancing allow it. The methods and criteria for participating, that require a reservation with a special app, will be published in time on the Ariel pages of the course, as well as all the teaching material (updated and divided by lesson and / or tutorial) and notices relating to any update linked to the evolution of the legislation imposed by Covid-19
Programma e materiale di riferimento
Il programma e il materiale di riferimento non subiranno variazioni.
Program and reference material
The program and the reference material will not change
Verification of learning and evaluation criteria
Written test of exercises lasting 30 minutes.
It is also provided, upon reasoned request, the possibility of taking the exam in oral form.
The tests are carried out through Microsoft Teams following the general indications provided by the University. The specific details of the procedure (turns, rules, etc.) are reported in Ariel.
The following will be evaluated: knowledge of the principles of: chemical nomenclature, calculation of molar concentration and pH in various solutions, oxidation-reduction balance, use of specific heat, use of the equilibrium constant and colligative properties, use of the chemical kinetics.

Assessment methods and Criteria
The assessment of the actual achievement of the expected learning results by the student takes place through a written test of exercises and open-ended questions lasting two hours only at the end of the course (two sessions). Classified students can possibly ask for an interview to improve their grade. If the outcome is not favorable, the student takes an oral exam in subsequent exam sessions.
The following will be generally evaluated: knowledge of the principles of: chemical nomenclature, calculation of molar concentration and pH in various solutions, redox balance, use of specific heat, use of the equilibrium constant and colligative properties, use of chemical kinetics.
To take the exam, you must register by the deadline set on the SIFA (http://www.unimi.it/).
The evaluation is expressed by a mark out of thirty.
The vote is communicated to each individual student by automated e-mail from the university minutes.
Further information on the course (exam sessions, etc.) can be found on ARIEL and the teacher's website http://users.unimi.it/thalasa/dimitrios2.htm
