Monday, March 23, 2015 Homework: NONE! Objective: We will determine mole ratios from chemical equations. Catalyst: -What do the amounts of each ingredient of a recipe tell you? -If you were going to double a recipe, how could you use the amounts in the original recipe? -If you were to half the recipe?

Agenda Catalyst Announcements S’more Stoichiometry Exit Ticket

S’more Stoichiometry Work in partners MUST complete both sides of the worksheet Before you ask Ms. Kline a question, READ, ask your partner, think it through!

S’more Stoichiometry What does the coefficient in front of each ingredient for the s’more equation tell us? What does the coefficient tell us in a chemical equation?

Exit Ticket What was the most difficult part of the activity today? What part of the activity was easiest to understand? How well did you try to work ON YOUR OWN, even when the problem was hard?

Monday, March 23, 2015 Homework: NONE! Objective: We will determine what factors affect wave speed. Bellringer: What predicts how quickly a wave travels? List at least three different possibilities, even if you aren’t 100% sure. A

Exit Ticket What are: 3-things you learned about factors that affect the speed at which waves travel 2-things you wonder about wave speed that we haven’t talked about yet. 1-question you have about sound.

Tuesday, March 24, 2015 Catalyst: Please answer your catalyst on a notecard. What was the mole ratio of a s’more “reaction”? If you had 6 moles of chocolate, how many s’mores could you make? If you had 5 moles of marshmallows, how many graham crackers would you need? Homework: NONE! Objective: We will determine mole ratios from chemical equations and convert from Mole A to Mole B. B

Agenda Catalyst Announcements Mole Ratio & Conversion Practice Exit Ticket

Exit Ticket 1) What is the mole ratio of: a) 4 P + 5 O2 P4O10 b) C3H8 + 5 O2 3 CO2 + 4 H2O c) 2 NaCl + F2  2 NaF + Cl2 2) Using the equations above: a) If you react 8 moles of P, how many moles of P4O10 is produced? b) If you react 6 moles of NaCl, how many moles of NaF would you produce?

Wednesday, March 25, 2015 Catalyst: C3H8 + 5O2  3CO2 + 4H2O For the equation above, list: A) Mole Ratio B) If you had 15 moles of O2, how many moles of H2O could you produce? C) If you produced 36 moles of CO2, how many moles of C3H8 reacted? Homework: NONE! Objective: We will determine mole ratios from chemical equations and convert from mole to mole and mole to gram. C
