CH42 – Recap and Review

Dates

• P4 – Friday, December 8th
• P5 – Friday, December 8th
• P7 – Monday, December 11th

PART I – GROUP QUIZ

Overall Structure

• students work in pairs! (one grade for both students)
• students given formulas of four substances
• students also given information about a physical property for each
• students need to match the substance identity to the information
• students will use information about IMF and polarity to identify

Building Questions to Answer Quiz (also provided on quiz sheet)

• Draw the Lewis Dot Structure
• Draw a 3D version of the molecule
• Identify the shape geometry around each central atom, including bond angles
• Build the molecule (check with the Quinton at this point)
• Identify (draw) the bond polarities and overall polarity in each molecule
• Identify the type(s) of IMF present in a pure sample of each

PART II – REVIEW FOR FINAL EXAM

• Unit 1 – The Atom
• Unit 2 – The Electron
• Unit 3 – Nomenclature
• Unit 4 – Chemical Reactions
• Unit 5 – Bonding
• Unit 6 – Phases

Sample Ideas

• sulfur-33 with a (-2) charge | subatomic particles
• iron (III) nitrite formula
• balance the reaction between lithium chloride and silver nitrate
• configuration of sodium ion
• shape of nitrate ion
• compare boiling point of water and carbon dioxide

Strategies (from the person WRITING THE EXAM)

• review past quizzes and tests
• review in-class notes
• syllabus objectives & practice problems
• BEWARE OF GROUPTHINK: shared docs / Grext
• Email Quinton

Homework

• Study for the Final
• Note: details for exam structure coming
• Note: I will provide sheet of ions / metals on the final
• Note: I will provide solubility rules on the final
