02 - Atomic weight, molecular weight, mole, composition percantage, empirical formula, molecular formula.

03 - Inorganic compounds: oxides, hydroxides, acids, hydrogen compounds, salts.

04 - Chemical reactions: balancing, yield, stoichiometry.

05 - Atomic structure: orbitals, electronic configuration.

06 - Periodic table of the elements, periodic properties, octet rule.

07 - Chemical bond: classification (intramolecular, intermolecular).

08 - Covalent bond, molecular geometry: VSEPR model, molecular polarity.

09 - Valence bond theory, elements of hybridation model.

10 - Ionic bond and metallic bond.

11 - Redox reactions.

12 - Intermolecular interactions: Van der Waals forces, hydrogen bond.

13 - Physical states: solid, liquid, gas. Changes of state.

14 - Solutions: solute-solvent interactions, concentration measures.

15 - Strong electrolytes, speciation, colligative properties.

16 - Chemical thermodynamics: enthalpy, entropy, free energy.

17 - Elements of kinetics: activation energy and catalysis.

18 - Chemical equilibrium. Equilibrium constant, Le Chatellier principles.

19 - Acid and bases in aqueous solution: pH calculation of solution containing strong or weak acids or bases.

20 - Saline hydrolysis.

21 - Buffer solutions and pH measurement techniques.

22 - Solubility equilibrium: saturated solutions, solubility and solubility product.

None

• Knowledge and understanding ability. Student will have to be able to describe the microscopic and macroscopic properties of the matter. In particular, they will able to master the concepts of mole, concentration, pH, solubility and chemical equilibrium. The achievement of these abilities will be tested through an oral examination.
• Application of knowledge and understanding. Student will have to be able to utilize the correct chemistry language, and to apply the stoichiometric calculation in order to determine the equilibrium state of a chemical system (yield of a reaction, pH of a solution, solubility of an insoluble electrolyte). The achievement of these abilities will be tested through a written examination.
• Judgement autonomy. Student will have to be able to estimate the role played by the substances composing a chemical system in determining its physical-chemical properties. This knowledge will be essential in order to interpret the behavior of more complex systems tackled in the next teaching. The achievement of these abilities will be tested through the written examination and oral questions aimed at estimate them.
• Communication ability. Student will have to be able to clearly describe the physical-chemical phenomena learned in the course with appropriate language and examples.
• Learning ability. Student will have to be able to grow autonomously and critically their scientific knowledges by using the teaching material provided by the teacher and any other book or scientific article provided by themselves. These abilities will be stimulated by the teacher proposing and resolving numeric problems.

The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it

The course foresees some hours of facultative stoichiometric exercitations in addition to the 56 foreseen.

Teaching

The course will consist of both lectures on the basic concepts of Chemistry and problem solving activities that help the student to identify structure and shape of common chemical species.

The teaching material prepared by the lecturer in addition to recommended text books (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform > blended.uniurb.it

Attendance

The frequency is not mandatory. Basic knowledges of mathematic and physic are requested.

Assessment

The assessment of the learning provides a written and an oral examination

The aim of the written examination is to verify the student skills with respect to the balance of a chemical reaction, to the stoichiometric calculus, to the calculus of the concentration of a solution and its related properties, the quantification of reagents and products in a chemical equilibrium, paying particular attention to the acid-base reactions and to the pH. The written examination consists of eight exercises: one related to design a molecular structure of a species and the indication of the geometry of the species; one related to the balance of a redox reaction; two nomenclature exercises in which must be indicated the molecular formula of three species knowing the systematic name and viceversa; two stoichiometric exercises with the calculus of the concentration of the solutions; one related to the stoichiometry of the chemical reactions; one related to the pH of a solution. The written examination will be judged by a qualitative result (sufficient, good, very good, optimum)

The aim of the oral examination is to verify the student preparation with respect to the writing of a chemical formula, to the prevision of the chemico-physical properties of the main inorganic compounds (oxides, hydrides, acids, bases, salts) as well as of the theoretical concepts, explained during the course. The student must be able to furnish appropriate examples concerning each argument to demonstrate the full comprehension of it.

The oral examination will be judge with a thirtieth vote in which the written examination will be taken into account.

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.

Teaching

The program and teaching materials are the same for both attending and non attending students. All this material is available on the institutional Web site.

The teaching material prepared by the lecturer in addition to recommended text books (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform > blended.uniurb.it
