The course aims to provide the student with basic general and inorganic chemistry knowledge, taking into account the theoretical and applicative aspects. The main goal is to allow the student to understand and analyze the matter, its properties as well as its transformations under the chemical point of view, mainly considering the biotechnological field. In particular, the student will be able to use the chemical language, to understand and use correctly the molecular formulae and to predict the chemical-physical properties of a compound as its reactivity, on the base of its structure and its elemental composition. This will be pursued paying particular attention to the chemical bonds, chemical reactions, main interactions in the molecular systems as well as aqueous solution chemistry.

D1 – Knowledge and ability of comprehension. 

The student will have the knowledge to analyze the properties of the matter, highlighting the relation among formula, geometries and molecular properties. He will have to know the principles at the chemical bond, the nomenclature of the inorganic chemical compounds,  foresee and understand the acid-base and redox behavior of the main compounds, the principles of the chemical equilibria and of the chemical reactions as the acid-base and redox reactions, the atomic and molecular structure, the foundations of the periodic tables with its periodic properties, the main properties of gases, liquids and solids, the intermolecular forces, the main foundations of the thermodynamic, of the chemical kinetic and of the electrochemistry. He will have the skill with the concepts of the mole, the concentration of the solutions, the pH and the solubility. In addition, he will have to know the numerical techniques to describe the equilibria, the reactions. These knowledges will be checked by oral questions.

D2 – Ability to apply knowledge and comprehension. 

Student will have the ability 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 knowledges will be tested through a written examination.

D3 – Autonomy of judgement. 

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.

D4 – Application skill. 

Student will have to be able to clearly describe the physical-chemical phenomena learned in the course with appropriate language and examples.

D5 – Learning skill. 

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

Teaching

The course consists of both lectures on the basic concepts of Chemistry and problem solving activities that help the student identify structure and shape of common chemical species and tackle stoichiometric problems when applied to chemical reactions.

Students can attend the lectures asking explanations to the teacher  

Innovative teaching methods

Debate: Students will be engaged in regulated debates on certain topics, to deepen into the topics in order to better understand them

Attendance

Optional

Basic knowledge of mathematics and physics are a prerequisite

Course books

Fusi, Giorgi, Lippolis, Zaccheroni Chimica: principi generali con esercizi. Idelson Gnocchi editore; ISBN: 9788879476539

Assessment

The final exam consists of both 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 (scarcely sufficient, sufficient, good, very good, optimum). The passing of the written exan will allow access to the oral one.

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 judged with a thirtieth vote in which the written examination will be taken into account

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
