Learning outcomes of the course unit
Knowledge and understanding:
At the end of the course the student will have integrated his knowledge about natural phenomena governing the transformation of matter, will have a complete overview of the laws governing the structure of atoms, molecules and compounds; know the theoretical reasons that are at the basis of the energy balance during the transformations of matter, will know how to obtain electrical work by processes of redox transformations.
Applying knowledge and understanding:
At the end of the course the student will have developed the ability to understand some physical and chemical characteristics of the substances, such as state of aggregation and volatility, hardness and fragility based on the knowledge of their structure. He will know how to quantify spontaneity of chemical and electrochemical processes and quantify the mass and energy balance during these transformations.
By the end of the course, the student should be able to evaluate, with critical mind, the experimental measurements of chemical reactions
By the end of the course, the student should be able to clearly present the experimental results of chemical reactions.
Solid knowledge in basic mathematics and physics is recommended

Assessment methods and criteria
The examination is based on a written questionnarie and an oral exam. The examination is weighted as follows: 30% written lab report (proper analysis of the experimental data 20%, clarity in presenting the results 10%); 70% oral exam (theory questions 20%, application of theory also to original problems 20% and speaking ability 30%).
Attendance strongly recommended
