11/1/2015Template copyright Types of Chemical Reactions A. Synthesis Reaction – 2 or more simple substances combine to form a more complex substance

11/1/2015Template copyright Types of Reactions Generic Example: A + B  AB Real Example: 2H 2 + O 2  2H 2 O *More than 1 reactant, only 1 product

11/1/2015Template copyright Types of Reactions B. Decomposition Reaction (opposite of synthesis) – a more complex substance breaks down into 2 or more simple substances

11/1/2015Template copyright Types of Reactions Generic Example: AB  A + B Real Example: 2H 2 O  2H 2 + O 2 *Only 1 reactant, more than 1 product

11/1/2015Template copyright Types of Reactions C. Single Replacement Reaction – a single element replaces another in a compound

11/1/2015Template copyright Types of Reactions Generic Example: A + BC  AC + B Real Example: Zn + 2HCl  ZnCl 2 + H 2

11/1/2015Template copyright Types of Chemical Reactions D. Double Replacement Reaction – parts of 2 compounds switch places to form 2 new compounds

11/1/2015Template copyright Types of Chemical Reactions Generic Example: AB + CD  AD + CB Real Example: AgNO 3 + NaCl  AgCl + NaNO 3
