Get Ready For Classifying Reactions!

• In your journal, turn your paper sideways
  (landscape) and make 5 columns across the entire
  page. Write the following headings across the
  top Synthesis, Decomposition, Single
  Replacement, Double Replacement, Combustion

2
Types of Chemical Equations

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

3
Synthesis Reaction

• Two or more substances react to form a single
  substance.
• One product
• A B ? AB

4
Decomposition Reaction

• A single compound is broken down into two or
  more simpler products.
• One reactant
• AB ? A B

5
Single Replacement Reaction

• Atoms of a more reactive element replace the
  atoms of a second element in a compound.
• A single element and a compound are on both
  sides of the eq.
• AB C ? AC B

6
Double Replacement Reaction

• Occurs when two compounds switch partners.
• Only compounds are on both sides of the equation.
• AB CD ? AD CB

7
Combustion Reaction

• Oxygen reacts with a hydrocarbon (CxHy) to form
  carbon dioxide and water.
• (Technically, reaction of any substance with O2
  that is exothermic.)
• CxHy O2 ? CO2 H2O

8
Sorting Activity

• With one partner, sort the strips you are given.
• Have your teacher approve your work.
• Copy the strips into your paper columns.
