1. Single Replacement Reactions
A sad story!

2. Definition
Single Replacement is a reaction in which an element and compound (or solution) yield a new element and new compound (or solution)
The reactants are an element and compound and the products are a different element and different compound

3. Generic Word Equation
Element + Compound yields New element + New compound
Must use the Activity Series to check to make sure that it does occur.

4. Algebraic Equation
A + BZ  B + AZ Or

5. Examples
Sodium Chloride (s) + Fluorine (g) Sodium Fluoride (s) + Chlorine (g)
Does this work? Why?
Why does the Fluorine replace or not replace the chlorine?

6. Examples
Sodium Chloride (s) + Iodine (aq) Sodium Iodide(s) + Chlorine (g)
Does this work? Why?
Why does the Iodine replace or not replace the chlorine?

7. Why does the Zinc Replace or not replace the Copper?
Zinc (s) + Copper (II) Nitrate (aq)  Copper (s) + Zinc Nitrate (aq)
Does this occur?
Why does the Zinc Replace or not replace the Copper?
Why does the copper on the product side not have the Roman Numeral?

8. Why does the Iron replace or not replace the Aluminum?
Iron (s) + Aluminum Oxide (s)  Aluminum (s) + Iron (III) Oxide (s)
Does this occur?
Why does the Iron replace or not replace the Aluminum?

9. Does this occur? This is called Thermite!!!!
Aluminum (s) + Iron (III) Oxide (s)  Iron (s) + Aluminum Oxide (s)
Does this occur? This is called Thermite!!!!
Why does the Aluminum Replace or not replace the Iron?
Why does the Iron on the product side not have the Roman Numeral?

10. Why is Gold so valuable?

11. What is important to remember?
Use the Activity Series.
How the Activity Series works- The reactant element must be higher up on the activity series (hence more active) than the Product element.
Watch to make sure that charges are not with lone elements
Others?

12. Why a sad story?
This reaction is like a couple that goes to a dance and the lone element interrupts the couple and “steals” the date of the product element. We all feel sad for the element that is left alone at the end of the reaction. 
