1. Types of Chemical Reactions
Synthesis
Decomposition
Single-Replacement
Double Replacement
Combustion

2. Synthesis Two or more Reactants combine to form one Product
H2 + O2 --> H2O

3. Decomposition One Reactant Breaks Down into multiple Products
H2O2 --> H2O + O2

4. Single-Replacement
A metal (or H) in an ionic compound is replaced by an unbonded metal (or H2)
CuCl2+Fe -->FeCl2 + Cu
Mg + HCl  H2 + MgCl2

5. Single-Replacement
An unbonded halogen replaces a halogen in a compound
F2 + NaCl  Cl2 + NaF

6. Double-Replacement
• Two different metals (or H or NH4) in separate ionic compounds trade places
•AgNO3 + K2CrO4 -->
KNO3 + Ag2CrO4

7. Combustion!
A compound (CxHy) reacts with Oxygen, forming carbon dioxide and water
C3H8 + O2 --> CO2 + H2O
