Mr. Emrick Northwestern High School AP Chemistry/CITC Chemistry through Clark State Community College 2012-2013 School Year Introduction: The Advance Placement (AP) Chemistry/ CITC Chemistry through Clark State Community College course at Northwestern High School is a first-year college chemistry course taught on campus here at Northwestern High School. The students in this class have two options upon successful completion of the course. In May of 2013, students may take the AP Chemistry exam provided by the College Board Testing Services (approximately $80). The test is scored by the College Board and the score is sent to the colleges or universities indicated by the individual student. College credit may be awarded, at the discretion of the college or university, for a good score on the test. The students may also enroll at Clark State Community College and, at minimal cost and upon successful completion of the course, receive five (5) semester units of college credit. Class starts at 7:15 and unless you have prior permission, you will be counted tardy after that time. 2012-2013 Syllabus – 2nd Semester Topic Intermolecular Forces Solutions Subtopics Objectives Types of Forces Boiling Points Heat of Fusion Heat of Vaporization Vapor Pressure Phase Diagrams Solid State Describe the types of intermolecular forces and apply this to properties of solutions, solids and liquids by: Defining and giving examples of the intermolecular forces; Using the structure of a compound to determine its most relevant intermolecular force and applying this to making predictions of physical properties; Describing the types of and performing calculations involving crystal structures of solids.
