Objetivos

After this course it is expected that the student will know and understand the fundaments of general chemistry. The student should be able to recognize the atomic structure and chemical bonds, basic foundations of chemistry, with the aim of understanding the structure of matter and its transformations, as well as understand and to know how to implement qualitative and quantitative chemical analysis, distinguishing between the different chemical equilibrium. Understand the acid-base equilibrium, knowing how to use buffer solutions, titrations and acid-base volumetry. Although the essentially introductory character of this UC, it is intended that students acquire skills allowing them a better adaptation and understanding of problems involved in chemical processes in the subsequent UC, essential to access profession as professionals in Biotechnology in general and particularly in the pharmaceutical, agrochemical, food and biochemistry, or related fields, and in public services

Métodos de ensino e atividades de aprendizagem

In the theoretical classes, the fundamentals of general chemistry will be addressed in an essentially qualitative way to students in the 1st year of higher education. Whenever possible, the method of rediscovery and the use of models that make the concepts more real are used. In the theoretical-practical classes it is proposed that the student solve practical examples of the application of the concepts worked in the theoretical classes, with the support of the teacher.

Exam: 100%

There is no minimum grade in the tests, but the final average should be equal or higher than 9.5 values.

Distance learning format:

The general chemistry course unit can be completed entirely at a distance. However, since the assessment, in this format, is online, an oral test may be applied.
