This is an introductory course to basic concepts and principles of chemistry. Topics covered in this course include: stoichiometry; chemical bonding; properties of gases, liquids, solids and solutions; chemical thermodynamics and chemical kinetics; aqueous equilibria; electrochemistry.- Reference texts

Understanding of fundamental principles (see the topics covered in the course) and their application in solving simple problems in general chemistry. For example, students should be able to calculate: the yields of the products of a reaction; the concentration of solutions; the pH of acids and bases solutions; the enthalpy, entropy and free energy change of a chemical reaction from thermochemical data.- Prerequisites
Fluency in elementary algebra is highly recommended. Little previous knowledge of chemistry is assumed, though obviously it is extremely helpful.- Teaching methods
The course is organized as follows: twenty-five lectures (49h) on all subjects of the course devoted to the presentation of the basic concepts and twelve lectures (24h) showing how to apply fundamental chemical ideas to solve, properly selected, problems in general chemistry to help students to enhance their understanding of the main topics and to improve their problem-solving skills.- Other information

The final exam consists of two parts: written and oral. The written exam (90 minutes long) will contain a mixture of 20 multiple choice and open answer questions. The orals are taken within a week of passing the written test. In the oral exam, lasting approximately 30 minutes, students are expected to come prepared to answer questions covering the work of the entire semester. The final exam aims to verify skills and level of knowledge acquired by the student on the course contents.- Extended program
