Learning outcomes
For the course unit "General Chemistry II", the student will be able to • model chemical transformations; • perform stoichiometric calculations; • define and calculate the properties of solutions (concentration, pH, buffer, etc.); • critically demonstrate approximate pH formulae. • write and weight reaction equations (dissociation, acid-base, redox, precipitation, combustion, etc.); • describe and calculate the evolution of the acidity (pH) of a reaction medium; • define the basic concepts of thermodynamics; • justify states of matter using thermodynamic concepts; • use theoretical concepts to justify reactivity in general chemistry and predict the spontaneity of chemical reactions; • describe the state of dynamic equilibrium and its displacement; • calculate values for equilibrium constants; • demonstrate some thermodynamic formulas; • demonstrate and use kinetic concepts to describe the rate of reaction; • use chemistry equipment correctly to carry out laboratory manipulations; • use theoretical concepts to analyse, exploit and comment on experimental results;
Objectives
The objectives of this course are to • to give the student a rigorous basic training in certain aspects of general chemistry (acidity (pH); thermochemistry; kinetics); • explain and predict chemical transformations using different theoretical concepts; • to carry out an experimental approach; • solve problems using mathematical reasoning and tools; • interpret data presented in different forms (table, graph, text, etc.)
Content
The teaching unit focuses on the fundamental theories of chemistry. The presentation of the basic concepts and the main thermodynamic variables introduces the physico-chemical equilibria. The study of reaction kinetics highlights the phenomena of catalysis and the importance of reaction mechanisms. The study of the behaviour of the various compounds in solution and of ionic dissociation leads to the notions of pH, buffer solutions and the study of the evolution of pH during a reaction.
Teaching methods
Different approaches are used in this teaching unit: • The theoretical concepts are presented in the form of a lecture based on a powerpoint. The latter is made available to students on the university's website "webcampus"; • Exercises in small groups (about 30 students), supervised by an assistant, allow the theoretical concepts to be applied and deepened; • Practical laboratory work, carried out individually under the supervision of an assistant, allows the theoretical concepts to be illustrated and manipulated. They also allow students to learn the correct use of the basic equipment of a chemistry laboratory and the protocols to be followed to carry out simple manipulations. • Teaching methods may be adapted to comply with health requirements.
Evaluations
The teaching unit "General Chemistry II" consists of three learning activities: - the theoretical course - tutorials (exercises) (TD) - practical work (laboratories) (TP) Each of these learning activities is assessed. In the course of the term, the student • The student must bring a simple, non-programmable calculator without a cover to the examination. If the student is absent during a test, and if this absence is justified by a medical certificate submitted to the secretariat of the Faculty of Science no later than 5 working days after the end of the certificate, the student must retake the test at the end of the term, on a date to be communicated to him/her in due course. If the absence is not justified by a medical certificate, the student will receive a mark of 0/20 for this test. • must carry out practical work. Each practical session is evaluated by an entrance examination (1/4 of the points) and a laboratory report (3/4 of the points) which must be handed in to the assistant within the time limit specified by the latter during each practical session. The average of the laboratory evaluations constitutes 10% of the final grade of the teaching unit. In case of absence, if justified by a medical certificate, submitted to the secretariat of the Faculty of Science, at the latest 5 working days after the end of the certificate, the student must send an e-mail to "didactique.chimie@unamur.be" within three working days from the beginning of the absence to inform the secretariat of the absence and the date on which he/she will be able to recover the TP. If the student fails to do this, a mark of 0/20 will be awarded for the practical course concerned. Any absence not justified by a medical certificate will result in a mark of 0/20 for the practical course concerned. The final marks of the practical and practical courses are definitively acquired at the end of the corresponding activities. During the examination session at the end of the second semester (May-June), the student has a written examination on the whole subject of the course unit. This is an open-ended written examination with many exercises. During the examination, the student may not have access to any documents other than the questionnaire and answer form provided by the teacher. The student must bring a simple, non-programmable, uncovered calculator to the examination. The student may not carry or have within reach any connectable object. In order to receive credit for the course, the student must obtain an average grade of at least 10/20. The weighted average for the teaching unit is calculated as follows: written examination in session (70%), final mark acquired during the year for TD (20%), final mark acquired during the year for TP (10%). The assessment of the different learning activities may be adapted to comply with the health requirements, which could lead to a modification of the weighting of the different activities (lectures, tutorials, practical work) in the calculation of the final mark of the course. All changes imposed by the health requirements will be communicated to the students via the SCHIB119: General Chemistry II website. During the summer examination session (August) the student has a written examination on the whole subject of the course unit, if he/she has not validated the credits corresponding to this course unit in the previous session. The examination is an open-ended written examination with many exercises. During the examination, the student may not have access to any documents other than the questionnaire and answer form provided by the teacher. The student must bring a simple, nonprogrammable, uncovered calculator to the examination. The student may not carry or have within reach any connectable object. To validate the credits of the course unit, the student must obtain a weighted average mark of at least 10/20. The calculation of the weighted average mark is the same as in June. The TD and TP marks acquired during the year are retained.
