This module is not approved as a discovery module

Objectives

-To provide an introduction to the structure and bonding in atoms and molecules, salts and metals; atomic structure and properties as a basis for the systematic chemistry of the elements.
-To investigate the background to the gas laws, atomic and molecular theory, kinetic theory, chemical kinetics, chemical equilibrium, thermochemistry, and the behaviour of ions in solution, acids and bases. Chemical equilibria, pH and redox reactions. Minerals as chemicals.
-Development of knowledge and understanding of chemical theories related to study of the atmosphere, hydrosphere and lithosphere that constitutes our planet.

Learning outcomes
-Understanding of the nature of matter, atoms, chemical amounts and bonding, periodicity of elements;
-Understanding of acids, bases, chemical equations and pH;
-Inorganic reactions (group 1, 2 & 7), redox reactions and transition metals;
-Knowledge of organic compounds;
-Understanding of enthalpy, chemical equlibria, and rates of reactions.

Skills outcomes
-Students will be able to apply chemical principles in new situations
-Students will be able to describe, explain and interpret results in terms of chemical principles and concepts and be able to apply mathematical methods to solve problems in chemistry
-Students will have gained practical skills in preparing and analysing inorganic and organic compounds, measuring reaction rates, measuring pH and carrying out acid-base and redox titrations.

A minimum attendance standard is expected for lab sessions. Resits are not available for individual coursework elements in the module. Attendance is required for coursework elements which are linked to an assessment available only at that specific time, such as fieldwork, lab reports on specific labs, and midterms. Chemistry Lab competency – resit opportunity is available and will be assessed by the same methodology as the first attempt.
