Warm up 33 C3H8(g) + 5O2(g)  3CO2(g) + 4H2O(g) Calculate the mole ratio of Oxygen and Water How many moles of Water are created when 15 moles of oxygen react?

2 HW Check 3-4 Solid Silicon dioxide reacts with Hydrofluoric Acid (HF) solution to produce the gas silicon tetraflouride and water Write the skeleton equation Balance List the mole ratio of silicon dioxide and silicon tetraflouride How many moles of HF are required to produce 4 moles of silicon tetraflouride?

3 Homework 3-4 Google Classroom

4 Important Dates Monday 3-2 – Smore Chemistry Tuesday 3-3 – ACT (homeroom) Wednesday 3-4 – Demo / Reaction Stoich Thursday 3-5 – Quiz / Composition Stoich Friday 3-6 – Reaction Stoich / Mole conversion assessment

5 Today is March 4, 2014 Topic: Reaction Stoichiometry
Lesson Objectives: SWBAT 2.2.4 Analyze Stoichiometric relationships inherent in a chemical reaction 2.2.5 Analyze quantitatively the composition of a substance (empirical formula, molecular formula, percent composition, and hydrates) Essential Question: 2.2 Analyze chemical reactions in terms of quantities, product formation, and energy.

6 Agenda 3-4 Do Now HW Check White Board Review INM Stations (turned in)

7 White Board Molar Mass Review (aka formula mass)
1. Oxygen (by its self!) 2. NaOH 3. CaCOOH 4. KCl2 + 3He 5. Mg2(CaH2)3

8 Mole Ratio Review (white board)
3 MgCl2 + 2 Al → 3 Mg + 2 AlCl3 MgCl2 to Al MgCl2 to Mg MgCl2 to AlCl3 Al to Mg Al to AlCl3 Mg to AlCl3

9 Calculating Mass of A Substance
Balance equation Convert starting amount to moles Use coefficients to write a mol-mol factor Convert moles of desired to grams Pg 33

10 Learning Check 2 4 Fe + 3 O2 2 Fe2O3
How many moles of Fe are needed to react with 2.5 mol of O2? Pg 33

11 Learning Check White Board
4 Fe O Fe2O3 How many grams of O2 are needed to produce mol of Fe2O3?

12 Learning Check White Board
The reaction between H2 and O2 produces g of water. How many grams of O2 reacted? Tip! Write out the equation then balance BEFORE you do anything else!! Don’t forget your mole ratio …

13 Stations

14 TOTD 4 Fe + 3 O2 2 Fe2O3 How many grams of O2 are needed to produce 2.50 mol of Fe2O3?
