Learning Objectives
The course aim is to provide the basic principles for the study of atomic structure of matter, the conditions of formation of bonds, the chemical reactivity, the chemical equilibrium and the properties of the main elements. Knowledge of these concepts is of fundamental importance to undertake the study of subsequent courses characterizing the degree course

Learning Achievements (Dublin Descriptors)
At the end of course the student will have to show:
A) to know the fundamental principles of General Chemistry: the atomic structure, the properties of the elements and their ability to form compounds, molecular structures, chemical reactions, energy exchanges, states of matter, chemical kinetics, equilibrium in solution, the properties acid -bases, electrochemistry, the chemistry of the elements of the main groups
B) to have acquired applicative skills concerning balance reactions, stoichiometry and problem solving on aqueous solution equilibria (acids-bases, solubility product) and electrochemistry
C) to be able to assess and solve autonomously problems related to the course content
D) to have developed oral and written communication skills suited to the presentation of the concepts acquired
E) to be able to explore the topics in different contexts and autonomously
Teaching Material
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, Attendance, Course Books and Assessment
- Teaching
The course consists in lecturers and stoichiometry together with practical experiences to favor the comprehension.
- Attendance
Basic chemistry, mathematics and physics at the secondary school level
- Course books
Bertini I., Luchinat C., Mani F., Chimica, Casa Editrice Ambrosiana, Milano Speranza M., Chimica Generale e Inorganica, edi-ermes, Milano Cacace F. e Schiavello M., Stechiometria, Bulzoni, Roma
Slides of the course
- Assessment
Admission to the oral examination is conditioned by passing a written test consisting of questions of general chemistry and stoichiometry.
Students who have attended at least 75% of lessons may replace the written exam with two written tests in itinere
- 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.
Additional Information for Non-Attending Students
- Teaching
The non-attending students could ask for the didactic material furnished by the teacher during the lesson; in addition, the teacher is at their disposal for personal meeting to clarify the arguments.
