Pumpkin Pie Reactants


I hope everyone had a great thanksgiving!

On Tuesday we turned in our Copper and Silver Nitrate Labs, and our first set of problems in the "HomeFun Problem Set." Mr. Lieberman went over 2 of the homework problems, #67 and #68, before we turned the assignment in. We further reviewed over limiting reactants during class.
Soon after the review we took the Stoich Quiz #3 - Revenge of the Stoich. If you haven't noticed yet all the titles are related to Star Wars in some way.

Over the break make sure you do the Copper Cycle pre-lab.
If you need a copy of the lab here is the link: Copper Cycle

To help you get in the limiting reactants thanksgiving mood, here are the actually ingredients to make a pumpkin pie:
1/3 c. firmly packed brown sugar
1/2 c. sugar
1 tsp ground cinnamon
1 tsp ground ginger
1/4 tsp. ground cloves
1/2 tsp. salt
1/2 tsp. ground nutmeg
2 eggs
1 1/2 c. evaporated milk
2 c. pumpkin puree

4 c. sugar
5 tsp ground cinnamon
5 tsp ground ginger
6 tsp. ground cloves
