GENERAL CHEMISTRY. Objectives of the course are: to clearly present the basic principles of chemistry; to provide solid basis and knowledge for understanding the chemical events at the molecular level. Abilities: introduce the students to the use of structure-property concept. Ability in making judgements and driving conclusions from the results of his experiments. Communication skills: the students will be able to use a suitable chemical vocabulary in relation to the course arguments and methods. STOICHIOMETRY. the main objective of the module is to provide the necessary basic knowledge and tools to develop an appropriate problem-solving ability applied to stoichiometry problems related to General and Inorganic Chemistry, tarting from the recognition of the dependent and independent variables, the design of the resolution strategy and finally, in the critical discussion of the results. These skills and competences allow for the application of concepts learned in the theoretical module and form the basis for the successive laboratory course. LABORATORY. The course has the objectives to: develop basic knowledge on materials, equipment, basic operations and techniques of common use in the chemical laboratory; gain preliminary skills on preparation of inorganic compounds and their purification; experimental verification of the main chemical processes in aqueous solution; develop the student skill in the basic laboratory practices.

Fundamentals of mathematics.

General Chemistry: Classroom lectures, powerpoint presentations and guided exercises with open discussion. Stoichiometry: Classroom lectures, slide shows and guided exercises with open discussion. The module will be developed by slowly increasing the degree of complexity of the proposed stoichiometry problems in order to stimulate the capacity to link different topics. Students will be encouraged to actively participate to classes and
guided through individual or collaborative problem-solving activity in order to stimulate preparation progresses and regularly test them. This approach will also favor the development of the expected specific communication skills. Students will be encouraged to supplement in-class work with individual homework for a successful fruition of the course. Laboratory. Laboratory activities with related discussion. The learning progress monitoring involves individual report on each of the activities, including general discussion and stoichiometry tests.

Students with physical disabilities, Learning Disabilities or Special Education Needs can request specific services and tools via the Staff Sviluppo e Coordinamento Carriere e Servizi alle Studentesse e agli Studenti, consulting the University webpage: https://www.uniupo.it/en/services/servicesstudentsphysical- or-learning-disabilities.
Students with disabilities, learning disabilities or special education needs, once they have contacted the University Staff, can refer to the tutor in charge of the course to define the examination modalities, concerning academic aspects.

The exam is written and is composed of two parts. The first part, with a maximum duration of 2 hours, requires solving 6 stoichiometry exercises (2 problems worth 2 points each and 4 problems worth 1.5 points each). The maximum total score is 10 points. With a score of at least 6/10, students gain access to the second part of the exam, which, in addition to questions from the theoretical module, also includes questions about some laboratory experiments. The evaluation of the test and the corresponding assignment of points will be based on the ability to identify the unknown variables in a problem, to set up a rational and justified problem-solving strategy, and to correctly use chemical language and symbols. A passing grade is achieved by demonstrating the ability to apply these skills to the main topics of the course. The maximum score is obtained by applying these skills in all proposed exercises. Examples of exams are available on the DIR platform.
The second part (3 hours) consists of 15 questions (12 theoretical questions related to the concepts covered in the theoretical module and 3 related to
the laboratory module). For the 12 questions on the theoretical module, a passing grade is reached with a basic knowledge of the main theoretical topics
covered during the course. The maximum score for the second part is 20/30, with a minimum passing score of 12.
Regarding the three laboratory questions, each exercise is worth 1 point and will be given during the theoretical module exam, after the 12 theory questions. There is no passing threshold specifically for these 3 questions (as they are integrated into the theoretical exam), but the maximum score is
obtained with good knowledge of laboratory procedures and equipment. An evaluation will also be made during the laboratory sessions based on short daily reports, which can increase the overall grade by up to 0.5 points. The final exam grade is obtained from the scores achieved in the written tests of the course modules (max 10 points for the stoichiometry module and max 20 points for the general chemistry and laboratory module). Honors (“lode”) are awarded when maximum scores are obtained in both tests and when the answers to the open questions are excellent.
On the DIR platform, students will find, along with the course materials, examples of complete exam texts.
