WARM-UP 3/2/15 HAPPY MARCH! Balance the following equations Fe+ Cl2 → FeCl3 (b) Fe+ O2 → Fe2O3

Mole Ratio From the balanced equation, we can predict how much of a certain reactant that will react or a product that will produced. Here’s an equation: H2 + O2  H2O Step 1 – Balance: 2H2 + O2  2H2O

Mole Ratio Step 1 – Balance: 2H2 + O2  2H2O Step 2 – Read the problem. How many moles of water would be produced from 3.7 moles of hydrogen gas? Step 2 – Read the problem. How many moles of water would be produced from 3.7 moles of hydrogen gas?

Mole Ratio Step 2 – Read the problem. How many moles of water would be produced from 3.7 moles of hydrogen gas? Step 3 – Find the ratio 2H2 + O2  2H2O Hydrogen to water? 2 to 2 1 to 1

Step 4 – Set up the problem Mole Ratio Step 3 – Find the ratio 2H2 + O2  2H2O Hydrogen to water? Step 4 – Set up the problem   (Given) _3.7 _ _mol H2_ Number units Ratio___2 __ _ mol H2O__ Number units (desired) Ratio____2___ _ mol H2 _ Number units (given) (Given) _3.7 _ _mol H2_ Number units Ratio________ _ mol H2O__ Number units (desired) Ratio________ _ mol H2 _ Number units (given) (Given) ________ ______ Number units Ratio________ ______ Number units (desired) Number units (given) (Given) _3.7 _ _mol H2_ Number units Ratio________ ______ Number units (desired) Number units (given) (Given) _3.7 _ _mol H2_ Number units Ratio________ ______ Number units (desired) Ratio________ _ mol H2 _ Number units (given)

a) Fe+ Cl2 → FeCl3 Using Warm-Up 1) How many moles of chlorine would react with 2.8 moles of iron? 2) How many moles of iron (III) chloride would be produce? Fe+ O2 → Fe2O3 1) How many moles of iron would need to react with 10.2 moles of oxygen? 2) How many moles of iron (III) oxide would be produce?
