The overall objective of General Chemistry is to provide the fundamental scientific background and practical training in Chemistry that are the basis for the understanding of the world around us. A key general objective is the development of qualitative and quantitative problem-solving skills. Of comparable importance is to learn proper laboratory practices, execute experiments, interpret experimental results and draw reasonable conclusions. Specific learning objectives for this course include the development of conceptual understanding of: elctronic distribuition on an atom; the principal chemical bond theories; bulk properties and models of gases, liquids and solids; thermodynamic laws and their relation with equilibrium - entropy and free energy concepts; physical and chemical equilibria; acqueous equilibria; electrochemistry and chemical kinetics.

Lectures in continuos avaluation mode, problem-solving sessions and labs
It is required to obtain the frequency to the chair, which requires the achievement of two practical laboratory work, and the 2 tests or 1 final exam.
The final evaluation results from the application of the following calculation formula:
FINAL SCORE = average of two test scores (or final exam score)* x 0.8 + P score x 0.2
* = The average grade obtained in the two tests or the final exam will have to be compulsorily equal to or greater than 9.5.
where P score = lab report grade, affected by information from the 2 lab classes
Note: Lab score is retained just in the year when the lab work was done.
