2.  Learn how to balance equations through notes and white boards/markers.

3. Which of the following set of coefficients would balance the following equation? ___ Na2So4 + ___ Mg → ___ Na + ___ MgSO4 F 1,1,2,1 G 1,2,1,2 H 2,1,1,2 J 2,1,2,1 1. Pick a vocabulary word and KISS definition 2. Circle your answer and Justify your choice I. STARTER (write this under the date 10/20)

4. Remember… Law of Conservation of mass= matter can’t be created or destroyed (it can only change forms)

5. This applies to chemical reactions:  The same number of atoms of each element that exist before the reaction will exist after the reaction…therefore it is: Balanced

7.  1. Find yield sign, and draw a vertical line  2. List your elements on both sides of the line  3. Count the number of atoms for each element  4. Are the balanced? (Do they match)  5. Fix it!!!

8. Practicing balancing equations on board

9.  A downloadable app on a phone has a game. It has you begin with a certain number of shapes, and the goal is to rearrange them into a certain shape or pattern (like tangrams). You have to use all of the shapes to reach the goal. How does this relate to the law of conservation of mass?

10.  * When you drive up to Mcdonalds, you order food and pay them $5.00. How much money worth of food products should you get in return? How does this relate to the law of conservation of mass?  **7 th, 6 th, 3 rd, and 4 th periods: once finished with the ending-open your journals to October 11 th to be graded!
