Syllabus
Prerequisites: The student should master the unit of mass (mg, g, kg) and volume (mL, L, m3, dm3, cm3). Also, the student must have good knowledge on use of logarithms and exponential notation. Moreover, he should be able to solve equations of first and second degree.
Undergraduate knowledge of minimal physic laws. (mass, electrical charges, Coulomb's Law...)
Target skills and knowledge: To know and to be able to understand reference concepts and propaedeutic arguments regarding:
• the atomic nature of matter;
• the chemical bond;
• the properties of gases and solutions;
• the behavior of chemical reactions, with particular reference to those in aqueous solution (red-ox, acid-base and heterogeneous equilibria);
• the periodic table of elements, and the chemistry of selected elements.
Examination methods: Written and oral. Students must pass a written test with questions covering the whole activity.
Assessment criteria: A maximum of 30 points are awarded to written test.
A maximum of 30 points are awarded to oral exam.
The final vote is obtained by the weighed average of written test and oral examination, 2/3 and 1/3 respectively.
Course unit contents: (Numerical applications are required for the topics marked with an asterisk)
