3 5 Types of Chemical Reactions 1. Synthesis Reaction: Two or more elements/compounds combine to form a more complex product Example: Synthesis Reaction - A + B ----> AB 2. Decomposition Reaction: One chemical species breaks down to simpler elements/compounds. Example: Decomposition Reaction - AB ----> A + B 3. Single Replacement Reaction: An uncombined element replaces a less reactive element in a compound, creating a new compound and a single element. Example: Single Replacement Reaction - A + BC ----> B + AC 4. Double Replacement Reaction: Involves two ionic compounds (in solution) that trade cations, creating two new compounds. Example: Double Replacement Reaction - AB + CD ----> AD + CB 5. Combustion Reaction: A hydrocarbon (or other organic molecule) burning in oxygen, producing carbon dioxide and water. Example: Combustion Reaction - CH 4 + 2O 2 CO 2 + 2H 2 O + energy

Which of the reactions above requires heat in order for the reaction to proceed? 23) What do we call it when heat is taken in or absorbed as a reaction occurs? 24) Many of the double replacement reactions above produce a precipitate. What is a precipitate? 25) Compounds that usually form precipitates have (OH) -, Ag +, or (SO4) -2 in them. Identify the number of 5 reactions above that are double replacement AND form a precipitate with these ions. 26) What do we call the numbers that are used to balance a chemical equation? 27) Reaction #11 above is performed in a test tube and the tube becomes hot as the reaction progresses. What kind of reaction gives off heat? Name another similar reaction.
