Combustion

• Reactions that have hydrocarbons (CH4) and oxygen
  as reactants, and carbon dioxide and water as
  products.

Decomposition Reactions

• Starts with one reactant and ends with 2 or more
  products.

Examples

• 2KClO3 2KCl 3O2
• 2NaCl 2Na Cl2

10
Single Replacement Reactions

• One compound and a free element that recombine to
  yield a new compound and new free element.
