EXAM DESCRIPTION

Written and oral examinations.

ASSESSMENT METHODS

The written test is designed to establish only the minimum level of knowledge required to gain access to the next oral exam and does not have a numerical evaluation. It is based on a nine-question solution, both of a theoretical and numerical nature, similar to those discussed in the exercises and present in the appropriate section available in Aulaweb on the following topics: nomenclature of inorganic and organic compounds; Balancing exchange and redox reactions; Stoichiometric calculations; Application of the perfect gas law; radiochemistry; Electronic configurations of atoms, ionic compounds and biatomic molecules; Chemical bond; Thermodynamic and thermochemical; PH calculation for strong and weak electrolytes; electrochemistry; Chemical equilibrium; Status diagrams with 1 and 2 components; Electrical, magnetic and mechanical properties of materials; Chemical kinetics; metallurgy. The test is considered to be overcome with a number of exact answers greater than or equal to 5.

The oral test evaluates the basics chemistry knowledge necessary for the technological development of the process of transforming matter into safety and respectful of the environment. It is based on 3 questions of equivalent weight for evaluation purposes and drawn from the essential contents of the teaching related to: 1) the structure of matter; 2) transformation of matter; 3) relationship between structure and material properties.
