OBJECTIVES

2.1. Describe the 5 general types of reactions

2.2 Predict the products of the five general types of reactions.

KEY CONCEPT

There are 5 general types of reactions:1. Combination2. Decomposition3. Single Replacement4. Double Replacement5. Combustion

COMBINATION REACTION

Definition: A chemical change in which two or more substances react to form a single new substance

Example:

CHEMISTRY EXAMPLE

GUIDED PRACTICE PROBLEM #7

ON YOUR OWN #8

DECOMPOSITION REACTION

Definition: A chemical change in which a single compound breaks down into two simpler compounds.

Example:

CHEMISTRY EXAMPLE

GUIDED PRACTICE PROBLEM #9

ON YOUR OWN #10

SINGLE-REPLACEMENT REACTION

Definition: A chemical change in which one element replaces a second element in a compound.

Example:

CHEMISTRY EXAMPLE

GUIDED PRACTICE PROBLEM #11 A

GUIDED PRACTICE PROBLEM #11B

ON YOUR OWN

DOUBLE REPLACEMENT REACTIONS

Definition: A chemical change involving an exchange of positive ions between two compounds

Example:

CHEMISTRY EXAMPLE

GUIDED PRACTICE PROBLEM #13A

GUIDED PRACTICE PROBLEM #13B

ON YOUR OWN #14A & 14B

b. H2SO4 (aq) Al(OH)3

COMBUSTION REACTION

Definition: A chemical change in which an element or a compound reacts with oxygen, producing energy in the form of heat and light. Basically, a reaction involving fire!
