Causal reasoning, the ability to argue and algebraic skills and computation skills are needed in order to fully benefit from the course

Learning outcomes
The course aims to provide the foundation for a correct understanding and interpretation of chemical phenomena, upon which the technologies in use in engineering are based. The course is directed to the knowledge of the structure and properties of matter, creating a link between the microscopic and macroscopic world.
The course will furnish the skills needed to apply the knowledge acquired to the analysis and to the comprehension of chemical problems in an engineering context, through the use of laws and methods which represent the foundation of the chemical phenomena. These capabilities will be acquired by the student with the development of suitable exercises requiring the use of models and methodologies described in the lectures. The ability to apply the acquired knowledge will be assessed through a written exam followed by an oral exam.
The course is designed to stimulate and emphasize connections with the other disciplines, with the aim to improve the learning and communication capacities through the mastery of the basic scientific terminology.

Development of the examination
The assessment of the level of student learning is carried out at the end of the course by two tests: a written and an oral. To facilitate an ongoing commitment of the students, during the course there will be three partial tests of stoichiometry. There will be three problems in each test. The written exam is passed if the mark of the three partial exceeds 54/30. For those that do not exceed 54/30, or that do not have access to the partial tests, there will be a written exam. The written test consists in solving four problems onall the topics covered in the course. The written test is preparatory to the oral examination, for access to which the student must solve at least three problems properly. By accessing the oral exam, students will have the opportunity to measure their preparation with a written test on the theoretical part. The oral discussion is devote to deepen knowledge of the topics covered in the course, selected with regard to exploring the preparation of the student on the conceptual topics of the course. In case of a negative outcome of the examination, the student has to repeat the written test.

To successfully pass the assessment of learning, through the written and oral tests, the student must demonstrate that he or she has acquired the ability to solve chemical problems in a meaningful way, to have acquired familiarity with the concepts presented in the course, and to possess an adequate knowledge of fundamental chemical knowledge.

In the written test, students must demonstrate that they have understood and assimilated the logic of stoichiometric calculations. Problems are considered solved properly if the procedure is correct from the logical point of view and the relative error of the result does not exceed 1%, taking into account the significant digits theory. During the course, students are trained in problem solving and encouraged to make full verification of the results, as well as explaining the logic of each step. Students will also be encouraged to solve appropriate problems designed to develop original and creative solutions. Important is the student's ability to argue and reason causally during the oral examination.

The overall outcome of the evaluation will be positive if the student achieve sufficiency, or at least 18 points, in each of the two tests. The final grade is the result of the average of the marks obtained in the two tests. The honors will be given to students who having achieved the highest rating, have passed brilliantly both tests.
