Objectives
To homogenizer the knowledge of students with different backgroundsThe student should learn the contents of General Chemistry included in the program, to know how to do the experimental work and solve the proposed problems.
On successful completion of the module, students will be able to
a) apply fundamental Chemistry concepts in Engineering subjects.
b) understand simple chemical phenomena with impact in society.
b) solve simple problems in thermochemistry, chemical thermodynamics, ideal gases, chemical kinetics, acids and bases, solubility, electrochemistry and organic chemistry.
c) perform calculations related to chemical phenomena and the corresponding physical measurements.
d) perform simple lab tasks – weighting, transfer of liquids and solids, titrations, measurement of absorvances and determination of concentrations.
e) critically assess results.
On successful completion of the module, students will have improved interpersonal skills and the ability to study alone.
Prerequisites
The design of this course takes into consideration the expected high diversity of of first year students of Engineering regarding chemistry background.
