Objectives
This subject introduces a molecular perspective for understanding the
natural world and helps students to identify the fundamental concepts on
physical and chemical changes of matters. Throughout the course,
students visualise the physical and chemical changes through the
understanding of molecular behaviour. Studying this subject also helps
develop students’ analytical thinking for their lifelong learning.
Intended Learning
Outcomes
Upon completion of the subject, students will be able to:
CCN1110 General Chemistry I
(a) demonstrate the microscopic concepts of atomic structure and
molecular bonding as well as their relationships with the general
property trends of elements and compounds.
(b) understand the macroscopic properties and basic principles of
liquids and solutions.
(c) apply and incorporate the chemical principles and knowledge
learned to solve chemical problems and to appreciate modern
applications in real life.
(d) demonstrate the abilities in communication as well as skills in
problem-solving and analytical thinking.

Teaching/Learning
Methodology
Lectures supplemented with guided reading will be used to introduce the
key concepts of the topics. Lectures will provide theory-based teaching
on physical, organic and inorganic chemistry. Examples and references
will be given to students whenever appropriate. Tutorials will provide
students with opportunities to broaden, enlighten and reinforce the
general knowledge obtained in the lectures. Students will be involved in
problem-based activities, classroom feedback, and discussions in the
tutorials. Laboratory sessions will allow students to understand, verify,
and apply knowledge developed from the lectures.
Assessment Methods A variety of assessment tools will be used to develop and assess
students’ achievement of the subject intended learning outcomes.
