“TYPES OF CHEMICAL REACTION”

• A chemical reaction is a rearrangement of atoms in which some of the original bonds are broken and new bonds are formed to give different chemical structures.
• Law of Conservation of Energy 


  — can be created/destroyed
• Synthesis 


  — Two or more elements or compounds COMBINE to make a more complex substance.
• Decomposition 


  — Compounds BREAK DOWN into simpler substances
• Single Replacement 


  — Occurs when one element REPLACES another one in a compound.
• Double Replacement 


  — Occurs when different atoms in two different compounds TRADE PLACES.
• Combustion 


  — This compound must be a hydrocarbon: made of Hydrogen, Carbon, and Oxygen.

  — Oxygen will be a reactant, H2O and CO2 will always be a product.
• List the 5 types of chemical reactions:

  1. Synthesis
  2. Decomposition
  3. Single Replacement
  4. Double Replacement
  5. Combustion
