Annotation -
The plenary lecture "General chemistry" provides the basic knowledge necessary for further study of chemical subjects. Interpretation is performed in basic level (in some chapters simplified). The aim of the lecture is to understand basic physical-chemical terms, relations and methodologies and their importance and practical use, with a number of examples from the study of the structure and function of biologically important molecules. The lecture assumes basic knowledge of mathematics, physics, and chemistry at the level of average secondary school. The lecture of 3 hours per week is supplemented by 2 hours per week seminar.
The lecture takes place in person, in case of impossibility to attend the faculty or the impossibility of full-time teaching, the course will take place in the online environment Microsoft Teams.
It is necessary to log in to the Microsoft Teams platform with a faculty/university e-mail and a faculty/university login!

Requirements to the exam -
To obtain the credit, it is necessary to pass tests during the semester with a gain of min. 60% points. The tests contain numerical and theoretical examples focused on the topics discussed in the lecture and in the exercises and are written in the exercises.

Examination: The exam consists of a written and an oral part. The written part contains theoretical knowledge and numerical examples on the topics discussed in the lecture and in the exercises. Examples often aim at understanding the context. The condition for passing the written part of the exam and for proceeding to the oral part of the exam is to obtain 60% points. The oral part of the exam includes written preparation and focuses on theoretical knowledge and context in the topics discussed at the lecture and in the secondary school of physics and chemistry.
