June 2015 The Hong Kong Polytechnic University Hong Kong Community College Subject Description Form Subject Code CCN1111 Subject Title General Chemistry II Level 1 Credit Value 3 Medium of Instruction English Pre-requisite / Co-requisite/ Exclusion Pre-requisite 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. in Alignment with Intended Learning Specific assessment % Intended subject Outcomes methods/tasks weighting learning outcomes to be assessed a b c Continuous Assessment* 50 Test 25 12.5 Assignment 1 2 d June 2015 Group Assignment Final Examination 12.5 50 Total 100% *Continuous assessment items and/or weighting may be adjusted by the subject team subject to the approval of the College Programme Committee.
