 Chemistry 12:  We took notes on Hydrolysis to start, then we read section 4.13.  Unit 4 # 69 was assigned, and is due Thursday.  Time was given for Lab 20G, and we wrote a quiz on section 4.11, finding pH and pOH. 

Tuesday, March 16, 2021

Chemistry 12:  After a mini-review, we took notes on Calculating pH and pOH.  We read Section 4.11 and Problems 47-57 were assigned and are due tomorrow.  The Lab 20G Calculations and Follow-up Questions are due tomorrow too, but not the conclusion.  Please expect a quiz tomorrow on pH and pOH.

Career Life Connections 12 - Sign up for a Capstone Presentation on the noticeboard at the top of the stairs by the Elevator/Library.  Try to get it done by the end of Q3, see Mr. Gale if you have any questions.
