1 Synthesis Reactions 2 H 2 + O 2  2 H 2 O2 H 2 + O 2  2 H 2 O Two or more reactants combine to form one new product.Two or more reactants combine to form one new product.

2 Synthesis Reactions Example:Example: Sodium metal and Chlorine Gas combine to yield Sodium Chloride:Sodium metal and Chlorine Gas combine to yield Sodium Chloride: Na + Cl 2 NaCl22 Click here for a synthesis reaction video.

3 Decomposition Reactions 2 H 2 O 2  2 H 2 O + O 22 H 2 O 2  2 H 2 O + O 2 One reactant breaks apart and becomes two or more products.One reactant breaks apart and becomes two or more products. Click here for a decomposition reaction demo.

4 Decomposition Reactions Example:Example: Aluminum Oxide decomposes to yield Aluminum Metal and Oxygen Gas:Aluminum Oxide decomposes to yield Aluminum Metal and Oxygen Gas: Al 2 O 3 + O 2 Al2324

5 Combustion Reactions CH O 2  CO H 2 OCH O 2  CO H 2 O A hydrocarbon is usually burned with Oxygen gas to produce Carbon Dioxide & Water.A hydrocarbon is usually burned with Oxygen gas to produce Carbon Dioxide & Water.

6 Combustion Reactions Hint for balancing…Hint for balancing… C 4 H 10 + O 2  CO 2 + H 2 O Double the reaction!!! 81013

7 Single Displacement Rxns Or Single ReplacementOr Single Replacement Li + NaCl  LiCl + NaLi + NaCl  LiCl + Na The single element replaces an element in the compound to form a new compound.The single element replaces an element in the compound to form a new compound.

8 Single Displacement Rxns Metal replaces metalMetal replaces metal Cu + 2 AgNO 3  Cu(NO 3 ) AgCu + 2 AgNO 3  Cu(NO 3 ) Ag Or nonmetal replaces nonmetalOr nonmetal replaces nonmetal Example:Example: F 2 + CaCl 2  CaF 2 + Cl 2F 2 + CaCl 2  CaF 2 + Cl 2

9 Double Displacement Rxns Or Double ReplacementOr Double Replacement NaCl + KBr  NaBr + KClNaCl + KBr  NaBr + KCl Two compounds are the reactants and the metals switch with one another.Two compounds are the reactants and the metals switch with one another.

10 Double Displacement Rxns Watch out for Hydrogen, sometimes it acts as a metal!Watch out for Hydrogen, sometimes it acts as a metal! NaOH + HCl  NaCl + H 2 ONaOH + HCl  NaCl + H 2 O

11 Double Displacement Rxns When in lab, these reactions can produce precipitates, which are solid particles mixed in a liquid.When in lab, these reactions can produce precipitates, which are solid particles mixed in a liquid.
