Your homework due Jan 24 is posted. Good work on the solubility lab today. A few things to remember for this week:
Please write your regular concluding paragraph, as well as answer the 4 Postlab questions directly in your lab notebook under your concluding paragraph. Use the Google machine if you are unsure how to answer them.
Here is an EXTRA CREDIT question, which you may include with the other 4 Postlab questions in your lab notebook: What compounds/ions are actually in a bottle of store-bought ammonia? Why is there a debate about this?
Winter Break is Feb 4-8. No class this week. (Only one week of work will be due on Feb 14 for the two weeks you are out.)
You will have a quiz on Feb 14 after Winter Break over the common acids. There is a handout linked to the Homework webpage with a list of these. Happy Valentine’s Day! ❤️
I will see you next week! Have a great weekend! jb
You made it to Fall Break! You have one week of homework due on Oct 18 after Fall Break. There is not a new Prelab due because the Molecular Models Lab does not require one. You do have a Postlab due (5.2). Use p.152-153 to help you write it, especially the red box, include the two vocab words from book, also the words polar and non-polar, and the word “surfactant.”
Hopefully, things are starting to click by this point for you. If not, call/email/come see me ASAP with your questions.
The Chapter 4 Test will be open tomorrow through next Wednesday. Bring any math work to class next week. Here are some videos to help with Chapter 4 if you need it. Choose from any of the electron configuration videos.
Help session will be next Thursday, Oct 4, in my classroom at 2:30pm. Get some help before we move on with Chapter 5.
Nice job on the flame tests! Don’t forget to include the six words/phrases below from the board in your Postlab due Thursday (along with reading p84-87). If you don’t know what something means, use the Google machine or your textbook’s glossary. Be sure you identify your two unknowns in the paragraph as well.
The Chap 3 Test opens tomorrow at 8am and closes Wednesday at 10pm.
