Identifying Types of Reactions

Identifying Types of Reactions

• A Crash Course
• By Mrs. Volpe

2
What are we talking about?

• There are 5 types of chemical reactions.
• 1. Synthesis
• 2. Decomposition
• 3. Combustion
• 4. Single Replacement
• 5. Double Replacement
• If you can identify which type of reaction you
  have based on the reactants given, then you can
  predict the products of that reaction.

3
Synthesis Reactions

• Reactants Two elements
• Products One new compound

Example 2Ba O2 --gt2BaO
4
Decomposition Reactions

• Reactants One compound
• Products Two pieces (element, compound, or one
  of each)

Example 2KClO3 --gt 2KCl 3O2
5
Combustion Reactions

• A combustion reaction is a specific sort of
  single replacement reaction that ALWAYS gives the
  same products
• Reactants Hydrocarbon and oxygen
• Products Carbon dioxide and Water

Example C3H8 5O2 --gt 3CO2 4H2O
6
Single Replacement

• Reactants One element and one compound
• Products New element and new compound

Example Zn HCl ---gt ZnCl2 H2
7
Double Replacement

• Reactants Two compounds
• Products Two new compounds

ExamplePb(NO3)2 2KI --gt PbI2 2KNO3
