GENERAL AND INORGANIC CHEMISTRY WITH LAB. I

The course is one of the core training activities of the Degree Course, and allows the student to gain knowledge and understanding on the main concepts of Chemistry.
Educational objectives of the course are:
1) knowing the laws that govern general chemistry and chemical reactions;
2) knowing the chemical nomenclature;
3) developing the ability to solve problems of general chemistry (stoichiometry);
4) favoring and stimulating the use of a logical and deductive reasoning in the resolution of these problems, an approach of fundamental importance to face any problem in the scientific field;
5) developing the ability to expose scientific concepts and reasoning in a formal way, both orally and by writing.

1. Knowledge and understanding
i) to know the chemical nomenclature.
ii) Knowing the main laws and the main concepts of general chemistry.
iii) Knowing the approach methodologies to solve chemical problems.
2. Ability to apply knowledge and understanding
i) Knowing how to write the chemical formula of an inorganic material and/or assign the name to a chemical compound starting from the chemical formula.
ii) Knowing how to use the laws and concepts learned to solve theoretical and practical problems.
3. Judgment skills
i) To be able to evaluate the logical consistency of the results to which the application of the learned laws takes place, both from a theoretical point of view and in the resolution of stoichiometry problems.
4. Communication skills
i) Knowing how to communicate the knowledge learned and the result of their application using an appropriate terminology, both in oral and written.
ii) Knowing how to interact with the teacher and with the classmates in a respectful and constructive way.
5. Learning skills
i) Knowing how to take notes, selecting and collecting information according to their importance and priority.
ii) Knowing how to integrate the concepts and examples collected by the personal notes with the files provided by the teacher and the reference texts.
iii) Knowing how to critically consult the reference texts and the bibliography they contain.

The students should have a basic knowledge of mathematics and algebra (first and second degree equations, logarithms and exponentials).

The assessment of learning takes place through a written test. The test, to be performed in one hour and a half, consists of questions of theory and exercises of stoichiometry. During the exam the use of books, notes, electronic media is not allowed.

Teaching is organized in lectures including problem solving exercises.
In the Ca' Foscari "Moodle" platform, the teaching material projected in the classroom during the lessons and some model exercises for the preparation of the written exam are available.
