5 Reaction Types

• Synthesis
• Decomposition
• Combustion
• Single Replacement
• Double Replacement

3
Synthesis Reactions

• Two substances react to form a single product.
• X Y XY

4

• Simple compounds make more complex ones.

5
Decomposition Reactions

• A single reactant decomposes or breaks down into
  two or more products.
• A B C
• (decomposition of a metal chlorate or metal
  carbonate are the most common)

6

• More complex compounds make less complex ones.

7
Combustion Reactions

• One reactant (fuel) combines with oxygen to
  produce an oxide and water.
• Fuel O2 oxide H2O

8

• The substance reacts with O2 in an exothermic
  reaction.

9
Two Types of Combustion Reactions

• Incomplete combustion
• CxHy 02 CO H20
• Complete Combustion
• CxHy O2 CO2 H2O

10
Single Replacement Reactions

• One, more reactive element, replaces another.
• M AX MX A

11

• One atom takes the place of another.

12
Two Types of Single Replacement Reactions

• Single Replacement of a Halogen
• Z2 AX AZ X2
• Single Replacement of a Metal
• M AX MX A
• HINT LOOK AT 1ST REACTANT!!

13
Double Replacement Reactions

• A reaction in which the cations and anions of
  both reactants switch partners.
• AX DZ AZ DX

14

• Two atoms trade places.
