- Students finished making observations of the 6 powders and 3 unknown mixtures and did the heat test today. Based on your observations, which unknown mixture is Mrs. Claus’ recipe mixture?
- Do: work on your science fair projects! If you have questions, you can email me and I will check periodically
- Hand in ch3 Notes and Review Worksheet (marked, corrected)
- Students wrote the ch3 test on Moles (Stoichiometry, applications, etc…)
- If you are all up to date, have handed in all your assignments and labs for term 2, you have no homework! (yay!)
- If you want to read ahead and start on notes for ch4, you absolutely can! We have already completed about 75% of ch4 (Single and Double Replacement reactions, Molarity)
- Otherwise, enjoy your holidays! Merry Christmas! 🙂
- Hand in Lab 16D, prelab with equations.
- Do: Lab 16E – identify the ion in Part 1 and in Part 2. Hand in your guess by the end of class.
- Quick Review
- Activity – Testing the acidity/basicity of metal oxides and non-metal oxides. What is the pattern?
- I will be able to determine the pH of a salt solution. See block 5 notes here: Salt Hydrolysis
- Do: Prelab 20D data tables (modified) for Monday when we return to class! see instructions here: Lab 20D
- Warm up! Three questions: can you solve them? See a copy here: Review questions and an answer key here: Review questions answer key
- Hand in ch3 notes and review worksheet next class.
- Ch3 Test Outline: about 8 questions, all written. The focus will be on moles and applications (i.e. empirical and molecular formulas). You should know how to do the calculations for the 4 spokes of the mole wheel and how to use mole ratios.
- If you have questions, you can go to TNT after school on Thursday.
- If you still have assignments to hand in, please complete them by the end of this week!
- Case 1225: The Case of the Christmas Cookie Mystery – Day 1. Help Mrs. Claus figure out which batch of baking supplies holds the actual ingredients to her famous Christmas cookies.
- Do: Lab 16D. Check to see if your predictions were correct.
- Do: For each DIFFERENT precipitate, write a formula equation, complete ionic equation, and net ionic equation.
- Do: Prelab for 16E (the bonus mark lab!) You should read the instructions so you know what you are doing and make data tables to collect your information. See copy here: Lab 16E
- Go over ch3 review worksheet. Mark it (so I can see what is correct and incorrect) and do corrections (not just the correct answer but also try to identify what mistake was made). See answers here: Ch3 Review Worksheet Answers
3. I will be able to use molar volume to calculate the volume or moles of a substance. See class notes here: Molar Volume
4. Extra Review (mole basics): Moles PreTest 2016, Moles preTest 2016 answer key, Molarity PreTest Worksheet and the answers only are on the second page. For full answers to #1-3, see: Molarity Worksheet Pretest Answers. Note that for questions #4 and 5, the questions were changed.
- Students had an open-binder test on the composition and history of the atom.
