Chemistry Week 4 ✅


Prelabs are looking great. Post labs are getting better. Here are a few reminders for this week:

1- Chap 2 Test will be open Friday @ 8a – Wednesday @ 10p. You have 60 minutes.

2- Your Postlab should be labeled with 5 things: what, why, how, data, errors. The data this week is just observations about what happened.

3- for extra credit, email me at and tell me the name of the substance in your body that catalyzes the decomposition of peroxide. (Why does a wound bubble with peroxide- don’t say oxygen?)

4- Quiz Sep 13 on the first 36 elements. Know the symbols and names, spelled correctly. There’s a quizlet on the homework page.

Have a good weekend! jb
