1. FIVE TYPES OF CHEMICAL REACTIONS
Chapter 8 section 3

2. Most often produces C02 and H20 Example:
1. Combustion
Needs oxygen
Most often produces C02 and H20
Example:
AB + O2  C02 + H20 + heat

3. 2. Combination Two or more compounds/elements combine to form one.
Example
A + B  AB

4. 3. Decomposition One compound breaks into 2- 3 compounds/ elements.
Involves heat or electrical current
Example
AB  A + B Q

5. 4. Single Replacement Reactants exchange partners – one change Example
A + BC  AC + B

6. 5. Double Replacement Reactants exchange partners- 2 changes Example
AB + CD  AD + BC
