Plan for the Day Review balancing chemical equations Work on study guide for next Friday’s Chemistry Unit test

Homework: 1. Study - CFA Monday over: *Law of Conservation of Mass/ Balancing Equations *Signs of chemical reactions *Rate of reaction Look over the labs we’ve done recently. Look over your notes, too. 2. Chemistry Unit Exam next Friday, November 3rd. 3. Study guide due next Friday.

Time for a quick knowledge check about balancing equations Time for a quick knowledge check about balancing equations. Do your best. This will determine whether you get another balancing equations practice worksheet or get to work on your study guide. Stand up a textbook between you and the person beside you.

Write your name on the card, then copy and balance the following equation. Show your work. Turn the card face down when you are done. I will take up the card. ____Mg + ____O2 ____MgO

Let’s work on the study guide. It will be due for a grade next Friday Let’s work on the study guide. It will be due for a grade next Friday. Pace yourself. It’s a lot of work. Don’t put it off until the night before it’s due.

Essential Question: What are some key concepts related to chemistry?
