CHEMISTRY

Module GENERAL AND INORGANIC CHEMISTRY

The course introduces the fundamental principles of atomic structure, chemical bonding, states of matter, and the properties and transformations of matter (General and Inorganic Chemistry).

Expected learning outcomes include a thorough understanding of: i) the atomic model and its application to electron configurations and the periodic table; ii) the thermochemistry and kinetics concepts covered; iii) acid-base theory; and iv) chemical equilibrium. Students are also expected to demonstrate the ability to: i) draw Lewis structures; ii) predict stereochemistry using VSEPR theory; iii) perform simple stoichiometry calculations (including balancing chemical equations).

Knowledge and understanding: Knowledge of the physical principles and fundamental concepts of general chemistry, the chemistry of s- and p-block elements in relation to their electronic and structural properties.

Applying knowledge and understanding: Upon completion of the course, the student will be able to apply basic chemistry concepts to practical problems that can be interrelated to agricultural production systems.

Making judgements: The student will be able to process the material learned and recognize "real-world" scenarios and specific problems where the chemical principles acquired can be applied.

Communication skills: Develop the ability to express ideas using appropriate terminology, in both oral and written contexts. Practical sessions will encourage group discussion and the ability to reach a conclusion by synthesizing the contributions that emerge during the discussion. By the end of the course, students will be able to describe topics in general, inorganic, and organic chemistry with articulate language and confident presentation skills.

Learning skills: Upon completion of the course, the student will be able to analyze, apply, and integrate the knowledge acquired with material learned in subsequent courses, particularly regarding scientific disciplines based on aspects and processes governed by chemical-molecular phenomena.

Lectures and practical sessions will be conducted using traditional face-to-face teaching methods, supported by pre-prepared PowerPoint slides that will be distributed to students throughout the course.

Should the course be delivered via a hybrid or remote format, necessary adjustments to the above arrangements may be introduced to ensure adherence to the syllabus and course program.

Attending the classes is not mandatory, but strongly recommended, as it facilities the learning process and contributes to the achievement of the learning objectives. https://www.di3a.unict.it/corsi/l-26-vee/regolamenti

To provide the fundamental skills and knowledge of general chemistry and stoichiometry, enabling students to acquire the basics required to understand and study subjects that demand familiarity with the scientific method and the ability to analyze chemical problems—specifically within the fields of technology and food safety.

The composition of matter: molecules and molecular compounds, ions and chemical compounds, chemical nomenclature, constitution of the atom, atomic weight and molecular weight, periodic table of elements, groups and periods, periodic properties of the elements, diagonal relationships.

 Fundamental laws of chemistry:  Lavoisier, Dalton, Avogadro's principle, and laws of combination. Atoms and their constituents: protons, neutrons, and electrons. Chemical bonding and intermolecular interactions.

· Chemical reactions: the concept of mole, chemical equations, balancing of simple reactions, definition of oxidant and reducing agent, oxidation number and redox reactions, definition of acid and base, acid-base reactions, quantitative meaning of chemical reactions, reactions at equilibrium and irreversible.

· The gaseous state: gas laws, equation of state of ideal gases, molar volume,

· State transitions: Gas-Steam-Liquid, critical pressure and temperature,
