Elements of chemistry and physical chemistry

A.Y. 2019/2020
Overall hours
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.

Prerequisites for admission
Knowledge of the rules of algebra, of the concept of fraction and proportion; concept of order of magnitude; the metric-decimal equivalences for the first part of the course. Minimum concepts of mathematical analysis for the second part of the course.
Teaching methods
Frontal lessons and classroom exercises with active student participation.
Teaching Resources
The teaching material consists of handouts provided during the course. Added to this are solved exercises and links to websites for chemical education. Details and downloadable material are available on the teacher's website http://users.unimi.it/thalasa/dimitrios2.htm and on ARIEl.
Finally, textbooks are recommended:
Fondamenti di chimica generale, seconda edizione" di Raymond Chang e Kenneth Goldsby (MacGraw and Hill); Stechiometria per la Chimica Generale P.M. Lausarot - G.A. Vaglio
PICCIN editore (for the first part)
Elementi di Chimica Fisica, PETER W. ATKINS, ed. ZANICHELLI (for the second part)
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 the teacher's website http://users.unimi.it/thalasa/dimitrios2.htm
