Chemistry 12:  Today we learned about how to determine whether or not a precipitation using K trial calculations.  I collected the yellow solubility lab.  Due Monday is Unit 3 # 53 - 63.  We also did a quiz like Unit 3 # 44-51.

Chemistry 12:  Unit 3 # 44 - 51 due Friday.  Unit 3 # 40 - 43 was due today.  Also due today was the Solubility Lab, which I did not collect.  Lab 16D will be due Monday, without a conclusion.

50.  K_sp = 1.1 x 10^-49

51.  1.2 x 10^-10 

Chemistry 12:  U3 # 21 and 25 (any 5 reactions that produce a precipitate)

Grade 8 Girls Volleyball:  Practice Sunday night from 7:00 - 8:30.  An important practice for those on the roster to play Monday, October 24th at 4:00, 5:00 and 6:00.  See change room bulletin board for roster.

Chemistry 12:  A progress report for you.  Keep working hard!  All  your efforts will pay off:)

Grade 8 Girls Volleyball:  Practice at 7:00 - 8:30 pm on Sunday night.   Wednesday and Friday practices are cancelled.  League at home on Monday at 4:00, 5:00 and 6:00.  See posted roster by PE changeroom door.  If you are not playing, you are invited to watch, cheer, and learn score-keeping or how to be a "down official".


Chemistry 12:  Today I checked Unit 3 # 1-9.  We did # 18-20d, and 10 - 13, which is due on Monday.  We started the Solubility Lab, and finished with a quiz.

Chemistry 12:  Unit 3 # 1-9.

Grade 8 Girls Volleyball:  Lunch Practice today.  No Practice on Wednesday or Friday, because I will be away.  I am working on a Sunday evening practice, so please stay tuned to my blog or the notice board outside the PE change rooms.  Monday night we had successful matches with a few instances of 3-contact volleyball.  In each set we were able to "jump and swing" at an attack ball 2 or more times, which is a good start.  I was asking for 5 attacked balls in each set, so there is work to do still:)

Chemistry 12:  Unit 2 # 52-58 due Friday.  Practice Test is due Monday.  Test on Equilibrium Unit on Monday.

52.  [SO3] = .56 M

52.  [SO3] = .56 M

#62 [N₂O₂] = .0938 M

Grade 8 Volleyball:  Practice on Friday at 3:30.

Chemistry 12:  Today we wrote a quiz on Unit II # 36 - 46 (skip 43), which the assignment from Friday.  Today we practiced Equilibrium Problems, and due on Thursday is Unit II # 47 - 51.  There will be an equilibrium unit test on Monday, October 17th.

48.  Keq = 3.0

49. a)  Keq = 0.013

49. b)  Keq = 0.93

50.  a) Q = 0.89, so shift to Products

50.  b)  Q = 7.5  so shift to Reactants

50.  c)  Q = 4 so no shifting required

51.  a)  Q = 7.5 so shift to Products

51.  b)  Q = 1.4 x 10⁴ so shift to Reactants

51.  c)  shift to Products

Grade 8 Girls Volleyball:  Practice today - big turn-out, but layers need to eat faster to get more serves in:)
We travel to Shuswap Middle School on Monday, October 17th, and I need parent drivers for this one since I will be at a conference in Vernon and will be approaching Salmon Arm from the south.    Players will leave at 2:15 from the RSS Parking lot.  Matches are at 4:00, 5:00, and 6:00.  We will be home by 8:00ish.  Parent drivers are required to complete some paperwork before they transport students - Clara at the front office can help with this.  Please call or email me if you think you can drive.  (250 -814 -8934, ggale@sd19.bc.ca)

Chemistry 12:  Unit II # 18-28 due next class.  Spend some time on Lab 19A, it will be due Friday.  Read the Pre and Post Lab discussion for hints on the equilibria equations.

Grade 8 Girls Volleyball:  Lunch practice cancelled today - too bad!  See you Wednesday at 7:00 pm and after school Friday for practice.   See the notice board by the change rooms for the list of travellers going to the next league day.

Chemistry 12:  Unit II # 17-27 (odds only) are due no Tuesday.  # 14 and 15 were collected today by me.  # 8-13 will be due on the double block this week.  On Tuesday, we will work on Lab 19A.

Grade 8 Girls Volleyball:  Today we left the school at 12:50 for league play in Enderby.  Ennnnderby. N.  Derby.  Enderby.  Practice will be on Tuesday at lunch.

Grade 8 Girls Volleyball:

Congratulations to the RSS players on Saturday that finished 6th at our Last spike Tournament!

On Monday, the 12 players listed below will leave class at 1:30 and board the Athletic Bus bound for Enderby.  We play matches at 4:00, 5:00, and 6:00 at A. L. Fortune Secondary, then we travel back to Revelstoke.  Expect to be picking the girls up from RSS at about 9:30  pm.  Bring water bottles, snacks, extra socks, black shorts, and if you want, some cash for food when the games are over.  We will likely stop at Subway.
