Chemistry 1

A.Y. 2020/2021
Overall hours
Learning objectives
The primary goal of the course is to provide a solid foundation in the basic concepts and facts of chemistry, particularly those needed for a successful understanding of other subjects for which chemistry is a prerequisite.
Expected learning outcomes
At the end of the course, students will be able to:
1. Recognize and name both the single chemical elements and the molecules formed by them;
2. Identify the bonds and chemical interactions underlying the formation of molecules;
3. Discuss the atomic structure, the electronic configuration of the elements and the periodic table;
4. Recognize and balance the chemical equation related to a given chemical reaction;
5. Calculate the pH, describe the properties of acids and bases, the acid-base equilibria, the constitution of buffer solutions and titration reactions;
6. Balance the oxidation-reduction reactions and calculate the potential and the electrode concentrations of an electrochemical cell by using the Nernst's law.
Course syllabus and organization

Single session

Lesson period
Second semester
If the sanitary emergency should continue, the lessons will take place remotely, mainly in synchronous mode by use of Zoom or Microsoft Teams. The asynchronous mode will be used for the study of some topics and of the slides that will be left available to students on the Ariel platform.

The program and the reference material will not change.

Assessment methods and criteria
The exam consists of a compulsory written test lasting 2 hours in presence, with distancing and quota if needed.
If the situation will not allow, it will take place remotely in the form that will be reported in the Ariel website at the end of the course.
Course syllabus
Structure of matter: Atomic structure. Atomic and molecular weights. Isotopes. Radioactivity. Mass defect.
Quantitative chemical relationships: Balancing redox reactions. Stoichiometric calculus. The chemical equilibrium. Le Chatelier's principle. Equilibrium constants.
Acid-Base reaction: Acids and bases (Arrhenius, Broensted, Lewis theories). pH. Buffer solutions. Hydrolysis. Acid-base titrations.
Atomic structure: Bohr's atomic model. De Broglie equation. Heisenberg's principle. On Schrödinger equation. Hydrogen atom. Many-electron atoms. The "aufbau" principle and the periodic table.
The Chemical bond: Ionic bonds. VSEPR Theory. The Covalent bond. The Hydrogen bond and the weak interactions. Bonding in coordination compound. Lattice energy and hydration energy. Ionic, molecular and van der Waals crystals.
Gases: Gas laws and the equation of state for ideal and real gases. Elements of the kinetic theory of gases. Solubility.
Thermodynamics: The first, the second and the third law of thermodynamics. Thermodynamic functions and chemical equilibrium.

Assessment methods and Criteria
The exam consists of a compulsory written test lasting 2 hours. In the same session, it will be possible to view the corrected task.
The written test focuses on the topics covered during the course and includes:
- the solution of 3 exercises, having contents and difficulties similar to those faced during the lessons.
- the answer to 3 theoretical questions.
For the purposes of the evaluation, the correctly carried out fractions of each exercise and theoretical question are calculated; if 1.5 exercises and 1.5 questions have been completed correctly, the student obtains a sufficient grade.
Any additional information on the assessment methods will be explained during the course.
Practicals: 24 hours
Lessons: 32 hours
Professor: Castellano Carlo
