Learning objectives
At the end of the course the students are expected to have acquired knowledge and understanding of General and Inorganic Chemistry concepts that will allow them to interpret the biological phenomena at molecular level.
In particular, with reference to the Dublin Indicators, the student at the end of the course will have pursued and obtained the underreported targets.
Knowledge and understanding: the student will know the fundamental concepts of chemistry necessary to interpret at molecular level the biological phenomena.
Application of knowledge and understanding: the student will be able to apply the techniques learned during the lectures in calculations and will be able to tackle the most common chemical problems.
Communication skills: the student will be able to express using a correct formal language, verbally and in writing, chemical concepts and ideas.
Making judgements: with the intellectual tools provided in the course, the student will be able to use the principles of mass and charge conservation, to predict the molecular shape and the properties of molecules, and to analyse chemical reactions based on thermodynamic and kinetic considerations.
Learning skills: at the end of the course the students should have acquired the basic concepts of chemistry and should be able to study by themselves without problems on advanced level chemistry texts and be able to expand, with a good level of independence, their knoweldge in the field.
Prerequisites
No prerequisites requested.
Course unit content
The course is made up of 9 ECTS, 7 of which devoted to the theoretical part and 2 to stoichiometry.
The lectures are divided into four Units:
Unit 1: Atomic-molecular Theory
The chemical tools. Atoms and elements. Compounds and molecules. Chemical reactions: an introduction. Reactions in water solutions. Thermochemistry.
Unit 2: Atomic structure and the chemical bondAtomic and molecular structure. Structure of the atom. Electronic configuration of atoms and periodic properties. Basic concepts on the chemical bond and on the molecular structure. – Further concepts on the chemical bond: orbital hybridization, molecular orbital theory and metallic bond.
Unit 3: Thermodynamics
The states of aggregation: gases and their behaviour. Intermolecular forces: liquids and solids. Solutions and their behaviour. The control of chemical reactions: thermodynamic and kinetic aspects. The principles of thermodynamics and their implications in a chemical context. Spontaneity of the chemical reactions. Enthropy and free energy. Chemical equilibrium. The chemistry of acids and bases. Buffer systems. Precipitation reactions. Thermodynamics of redox reactions. Electrochemistry.
Unit 4: Kinetics
Rates and mechanisms of chemical reactions – Chemistry of the elements and of their compounds: the s and p blocks and the transition elements of biological relevance.
The stoichiometry part includes:
Writing a chemical formula from the name of a compound and vice versa.
Balancing chemical reactions.
The concept of mole and its use.
Redox reactions. Equivalent weight. Normality.
Principles of volumetric analysis.
Equilibria in solution: calculation of the pH of various kinds of solutions.
Buffer solutions.
Hydrolysis.

Students who have problems with stoichiometry are advised to refer to the following text:

Teaching methods
The course is made up of lectures, supplemented by material accessible online on the site https://elly2024.didattica.unipr.it/. Impromptu tests will be taken during the year to check the students’ level of comprehension. The stoichiometry part will be carried out by presenting a series of examples at the blackboard followed by problems to be solved individually or in group, in the classroom or at home.
During the lectures questions concerning the subject under discussion will be posed and students are incouraged to intervene or ask further questions.
Assessment methods and criteria
Possibility to take an intermediate exam (tentatively in the second half of November), lasting 45 minutes. Those who pass the intermediate exam with a score of at least 18/30 will be allowed to take the remaining part of the program during one of the scheduled exam sessions.
Note: The partial exam will be valid ONLY during the following calendar year, and when registering for the exam on ESSE3, it will be MANDATORY to indicate in the notes that the partial exam was passed. No exceptions to these rules will be allowed. The final grade will be a weighted average of the grade received in the intermediate exam and the grade received in the second exam. The final grade can be accepted or rejected.
Alternatively, learning outcomes are assessed through a final written exam (1.5 hours) consisting of 13 open-ended questions, distributed as follows:
Four questions on atomic and molecular theory concepts (11 points)
Three questions on chemical bonding theory (6 points)
Four questions on chemical thermodynamics (10 points)
Two questions on chemical kinetics (3 points)
However, to pass the exam, it is not enough to accumulate 18 points; the student must obtain at least half of the points assigned to each of the four teaching units. If, in addition to answering all the questions, the exam is neatly presented and the student demonstrates good command of language, honors will be awarded.
