Tittel Sugar and Salt Solutions - Annotated Lecture Slides
Beskrivelse Learning goals for the Annotated Lecture Slides include the following. Students will be able to: Explain the difference between the conductivity of solutions of ionic and molecular compounds based on the presence or absence of freely moving charged particles Describe the atomic-level structural features of ionic compounds Describe the forces involved in ionic bonding Identify if solutions contain ionic or molecular compounds based on conductivity Identify if solutions contain ionic or molecular compounds based on atomic-scale representations Describe the bonding in ionic compounds of polyatomic ions Determine if a chemical compound is best described as ionic or molecular based on its chemical composition, specifically whether it contains metal and non-metal elements or not
