Presentation transcript:

Types of Reactions

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

Example: C3H8 + 5O2  3CO2 + 4H2O

Synthesis Reactions

Synthesis

Examples 2Na + Cl2 2NaCl Na2O + CO2 Na2CO3

Decomposition Reactions Starts with one reactant and ends with 2 or more products.

Decomposition

Examples 2KClO3 2KCl +3O2 2NaCl 2Na + Cl2

Single Replacement Reactions One compound and a free element that recombine to yield a new compound and new free element.

Single Replacement

Examples Fe+CuSO4 Cu +FeSO4 2Na + 2HCl H2 +2NaCl

Double Replacement Reactions Starts with 2 compounds as reactants. These recombine to form 2 new compounds as products. + +

Double Replacement

NaCl + AgNO3 NaNO3 + AgCl KOH + HNO3 HOH + KNO3 Examples C:\Documents and Settings\mswilliams\Local Settings\Temporary Internet Files\OLK1B5\types.htm
