Lab Day 2

Today we finished the Copper (II) Chloride lab. My partner and I determined that our iron that was used had a 3+ charge. The lab was fun and very helpful in practicing our stoichiometry skills and actually applying them to a real problem that we collected data for.

Exam Thoughts

I thought the exam was okay, but I think I could have prepared for it more. Next time I am going to do the problems in the book, all the practice test and watch videos on the topic. Hopefully next semester will go better!

Exam Moved to Tomorrow!

Thank you to Mrs. Frankenberg for moving the exam to tomorrow. The exam will be over everything we have learned in chapter 9, here are some links to help study for the test!

Copper (II) Chloride Lab

Last week we spent two days in lab. The first day my partner and I placed an iron nail in a jar of Copper (II) Chloride and water and let it sit over night. The next day we removed the nail and cleaned off the copper with hydrochloric acid and distilled water. It was cool to see all the copper that was left in the jar after cleaning it.
