General and Inorganic Chemistry with Lab

Goals
The aim of the course is to introduce the basics of chemistry from both a theoretical and a practical point of view. The course is splitted into two parts, with classroom lessons, stoichiometry practices and seven laboratory practices.

Acquired skills
Comprehension of the basic structure of atoms and molecules and of the basics of thermodynamics and kinetics.
To understand and solve any kind of stoichiometry problems. To identify and use lab facilities. To be aware of the security rules. To perform simple lab operations (to weigh, to prepare a solution, to crystallize, to filter, to carry out a synthesis). To draw up a report.
