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

5. 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

6. 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?

7. 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
