At the end of the course, the student will be able to : - Solve a numerical problem related to the stoichiometry of chemical reactions or thermodynamics (1st and 2nd principles) - Representing substances at the microscopic level using multiple semiotic systems - Determine the characteristics of substances at the microscopic level (electronic structure, chemical bonds, electronegativity, atomic radius, intermolecular forces) - Determine the characteristics of substances at the macroscopic level (solubility, boiling temperature, reactivity with other substances, state of matter) - Describe concrete applications in redox (batteries, etc.) or thermochemistry (self-heating capsules, etc.)
