Week of 3/24 Thermochem & End of Quarter

Monday: Today you completed the Heat of Combustion of Mg lab.  Lab is due April 7th.

Tuesday: Reviewed for test. Here’s the notes.

Wednesday: Test

Thursday/Friday: Music trip & AP Exam Review

Week of 3/17 Thermochemistry

Videos for the whole unit in 2 hours (or maybe longer…): From NMSI Part 1 and Part II (here’s the notes to go with it, which you already have some of).

HOMEWORK ANSWERS (except for ch. 9)

Monday: Snow day. Arghhh.

Tuesday: Review of calorimetry. Here’s the notes.  HW: textbook problems see unit outline

Videos:

From First year chem:

AP Teacher:

Wednesday:  First half: ways to theoretically calculate heat…Bond Enthalpy, Hess’s Law, Heats of Formation. Here’s the notes. SEcond half was determining calorimeter constant for a coffee cup.  I think we’ll do this a different way next year…instead of having you extrapolate back using the graph we’ll find some other mathematical way to do it (using Zumdahl lab manual)

Videos:

  1. Bond Enthalpy’s
  2. Hess’s Law
  3. Heats of formation

Thursday: Started with 3 MC AP questions on math we did the day before.  Next was some theory about internal energy, work and enthalpy.  Notes are in the same file as yesterday’s notes.  Second half we went through  calculating heat for physical changes (interpret heating curves, calculate heat for phase changes w/ temp change) and then did the heat of fusion of water lab.

Videos from first year chem:

Friday: We talked about the results of Wed. and Thursday’s labs, went through the calculation for heat of fusion lab and then started planning for the Heat of Combustion of Mg lab.

HOMEWORK ANSWERS (except for ch. 9)

Week of 3/10

Monday: First half of class we completed our bonding models for metallic, molecular covalent and network covalent.  (my lecture outline), Smart Board Notes.  Second half I was at an IEP meeting so I left some reading for you on alloys and carbon allotropes + some worksheets on identifying type of bonding + IMF practice.   The IMF practice was a little tricky when it came to HCl.  HCl is a polar compound, but strongest IMF is dispersion…how do you know that it doesn’t follow the rule? The worksheet gives the (g) symbol which means the substance is a gas…kind of indicating weak IMF, but if you said dipole-dipole on a test I would say you were right.

Tuesday: Jigsaw with physical properties.  Handed out powerpoint. 4 groups of 4 people. Each group had 2 words.

Wednesday: finished jigsaw.  Went through practice questions in power point/ general review. Last 3rd of class worked on pre-lab for Vapor Pressure lab.

Thursday: Did vapor pressure lab.  Note  for next year – large test tubes with white stoppers worked pretty well, but may need to buy new valves for pressure probe apparatus.

Friday: Test

Week of 3/3

Monday & Tuesday: Snow Days

Wednesday: Test

HW: Watch IMF video, do pg 2 in packet (concept map), 11.63, 11.103

Thursday: early release F and G cancelled

Friday: Reviewed IMF terms, went over concept map, notes on ionic bonding model (my lecture outline).
