Let’s make a foldable… Step 1: Hold your paper horizontal. Step 2: Fold your paper in half from left to right. Step 3: Unfold your paper. Step 4: Fold each side of your paper to the crease in the center of your paper. Step 5: Cut the paper to make two flaps on the left side and two flaps on the right side.

Types of Chemical Reactions…In the same way that elements are divided into

groups based on their properties, reactions can be classified on what occurs during the reaction.

There are four types we will learn:1. Synthesis

2. Decomposition3. Single-displacement4. Double-displacement

Let’s make a foldable…

Step 1: Hold your paper horizontal.Step 2: Fold your paper in half from left to right.Step 3: Unfold your paper.Step 4: Fold each side of your paper to the crease

in the center of your paper.Step 5: Cut the paper to make two flaps on the

left side and two flaps on the rightside.

On the upper left flap…

Synthesis Reaction:(inside) 2 or more substances combine to

form one new compoundExample:

Page 5: Types of Chemical Reactions Chapter 13, Section 3.

On the lower left flap…

Decomposition Reaction:(inside) a single compound breaks down to form 2

or more simpler substances Example:

Page 6: Types of Chemical Reactions Chapter 13, Section 3.

On the upper right flap…

Single-Displacement Reaction:(inside) an element replaces another element that

is part of a compound Example:

Page 7: Types of Chemical Reactions Chapter 13, Section 3.

On the lower right flap…

Double-Displacement Reaction:(inside) ions from two compounds exchange

places Example:

Within your group, assign the following roles:

1. Recorder (write down responses)2. Information Gatherer (look up answers)3. Time Keeper (make sure group’s on task)4. Reporter (be ready to talk in front of class)

Page 9: Types of Chemical Reactions Chapter 13, Section 3.

Questions:1. What type of reaction does the following

represent? FeS + 2HCl FeCl2 + H2S2. Describe the difference between single- and

double-displacement reactions.3. Write the balanced equation in which

potassium iodide (KI) reacts with chlorine to form potassium chloride (KCl) and iodine.

Hint: Remember diatomic elements!!!

Turn in one paper…with all names on it!!!
