TRAINING REQUIREMENT CHEMISTRY 2

The course aims to provide the minimum essential knowledge of Chemistry as an indispensable cultural and scientific foundation for understanding the course in General and Inorganic Chemistry.

With reference to the Dublin Descriptors, the activities designed to fulfill the Chemistry Additional Learning Requirements (OFA) contribute to the development of the following competences:

• Knowledge and understanding: students are expected to demonstrate knowledge and understanding of the fundamental concepts of general chemistry, with particular reference to the scientific method, matter and its states of aggregation, the distinction between substances and compounds, atomic structure, and the main subatomic particles. Students should also understand the concepts of atomic number, mass number, isotopes, atomic mass unit, mole, atomic and molecular mass, the fundamental laws of stoichiometry, the periodic organization of the elements, electron configuration, and oxidation number.

• Applying knowledge and understanding: students should be able to apply the acquired knowledge to the solution of simple problems in general chemistry and stoichiometry, determine chemical formulas, balance chemical equations, recognize and balance simple oxidation-reduction reactions, perform calculations involving quantitative relationships between reactants and products, and identify the limiting reagent.

• Making judgements: students should be able to interpret basic chemical information and correctly select the relationships, quantities, and procedures required to solve elementary problems in stoichiometry and atomic structure, while assessing the consistency and plausibility of the results obtained.

• Communication skills: students should be able to use the basic language of chemistry correctly, including the symbols of elements and compounds, chemical formulas, reaction equations, and the terminology related to atomic structure, stoichiometry, and the periodic table.

• Learning skills: students should demonstrate that they have acquired the basic knowledge and tools required to approach university-level chemistry courses with an appropriate degree of autonomy, applying fundamental concepts also to simple problems and exercises not previously encountered.

Information for Students with Disabilities and/or Specific Learning Disorders (SLDs)

To ensure equal opportunities and in compliance with current legislation, students concerned may request an individual meeting in order to arrange any appropriate compensatory and/or dispensatory measures, taking into account the learning objectives of the course and the student’s specific needs.

The teaching methods used during the course include lectures, participatory and/or cooperative activities aimed at acquiring basic knowledge of Chemistry. Practical exercises, individual research, and group work are also planned to develop the ability to apply the acquired basic knowledge.

In particular, the course includes 14 hours of lectures.

Basic mathematics, basic physics.

Attendance is compulsory for students who need to make up their OFA (Additional Learning Requirements).

Regular and continuous participation in the lessons will have a positive impact on the student’s final assessment and on their understanding of General and Inorganic Chemistry.

• The material provided on Studium

The exam consists of a written multiple-choice test and covers exclusively the topics addressed during the zero courses. Textbooks, formula sheets, course notes, or periodic tables are not allowed during the written test, nor is the use of mobile phones, even in calculator mode. Only the use of a calculator is permitted. Students must present themselves with a valid identification document.

Examples of Common Questions and/or Exercises

• Solving simple stoichiometric calculations

• Determining the empirical formula of a compound

• Interpreting and using the periodic table of the elements

• Determining the electron configuration of elements
