Learning outcomes

At the end of the course the student possesses the basic knowledge of chemistry and the scientific method, learned via significant examples and quantitative applications of the natural laws and the interpretative models. Moreover, the student gains the fundamental chemical principles concerning the atomic structure, the periodic table, the properties of the chemical elements, the chemical bond, the molecules and their geometries, the aggregation state of the matter. The student will be able to understand a chemical reaction, the balance of matter and energy, the homogeneous and heterogeneous chemical equilibria, the spontaneity of chemical reactions and their kinetics, as well as the use of chemical energy in order to produce electrical work. Moreover, students will gain an understanding and a knowledge of the fundamental concepts of stoichiometry and practical chemistry, via numerical exercises and laboratory sessions. They will acquire the skills necessary to work in a chemical laboratory and be able to correlate their experimental data with chemical reactivity.

Teaching methods

Lectures integrated with exercises and laboratory activities. The course is divided in three phases. The first phase introduces the objectives of the course and gives a brief description of the nature of matter and its transformations with the aim to learn the chemical language and nomenclature. The second phase presents the chemical phenomena and their quantitative handling with the help of numerical exercises. The third phase is devoted to the comprehension and interpretation of behaviour and phenomena, object of the second phase. For what concerns in specific the Laboratory activities, it consists of lectures and numerical exercises carried out in the classroom and practical activities in the chemical laboratory. Experiments will be documented by students individually in their own personal lab-books and the results will be discussed together. A tutor will be available to help students in solving exercises and override encountered difficulties

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme

Assessment methods

Assessment of the learning outcomes is carried out by a written test and an oral exam. The test, which includes problems, exercises and open answers, is passed with a score equal or higher than 18/30. Examples of problems and questions similar to those of the final exam are provided. Access to oral exam is possible after passing the written test. Oral exam is aimed at evaluating the knowledge and abilities indicated among the learing objectives of the course. The final mark is an average of the written and oral exam and takes into consideration both theoretical and laboratory competences in equal weight.
The final written test can be replaced by three tests taken during the course (one at about half of the program and the other at the end of the program). The average score of the two tests provides the final written mark.Registration to the written and oral exams is required through “Alma Esami” web platform, in observation to the stated deadlines.

Teaching tools

Blackboard and PowerPoint presentations for lectures. Documents and slides shown are made available to students by AMS Campus web platform. Experimental activities are planned in teaching laboratories; a workplace provided with basic instruments and glassware to is assigned each student.
