    • What’s in a name?
      The FIVE General Types of Chemical Reactions
    • Definition: A reaction in which TWO or more substances combine to form a SINGLEnew compound.
      Characteristics:
      General Formula: A + X -> AX
      Synthesis Reaction
    • Example of Synthesis Reaction
      Formula Equation: A chemical equation written in proper chemical formulas ONLY.
      Na + Cl2 -> NaCl
      Notice how the product, NaCl: is chemically different from both the reactants, Sodium - METAL, and Chlorine – GREEN GAS.
    • Additional Example of Synthesis Reactions
      Example #2:
      Fe + O 2 -> Fe3O2
      This is the chemical process we call, RUST.
    • H2O -> H2 +O2
      This reaction only takes place during electrolysis; when an electrical current is used.
      Non-Example of Synthesis Reaction
      ** The Electrolysis of Water - Movie
    • Definition: A reaction in which ONE substance breaks down to form TWO or more simpler substances.
      Characteristics:
      General Formula: AX -> A + X
      Usually occurs in the presence of heat or electricity.
      Decomposition Reaction
    • Example of Decomposition Reaction
      Example:
      CuCO3 -> CuO + CO2
      NOTE: We can easily tell the difference chemically between CuCO3 and CuO because of the CHANGE IN COLOR.
    • Additional Example of Decomposition Reactions
      Formula Equation:
      I4O9-> I2O6 + I2
    • Example #1:
      Al + Pb(NO3)2-> Pb + Al(NO3)3
      NOTE: The colors help you keep track of where the element is written in the equation.
      Non-Example of Decomposition Reaction
    • Definition: A reaction in which ONE element takes the place of another element in a compound.
      Characteristics:
      General Formula: A + BX -> AX + B
      Single-Replacement Reaction
    • Example of Single-Replacement Reaction
      • Example #1:
      Al + Pb(NO3)2-> Pb + Al(NO3)3
    • Additional Example of Single-Replacement Reactions
      Cu + AgNO3 -> CuNO3 + Ag
      ** Copper and Silver Nitrate Reaction - Clip
    • Non-Example of Single-Replacement Reaction
      Pb(NO3)2+ KI -> PbI2+ KNO3
    • Definition: A reaction in which appears exchange of atoms or ions between two compounds has occurred.
      Characteristics:
      General Formula: AY + BX -> AX + BY
      Double-Replacement Reaction
    • Example of Double -Replacement Reaction
      Pb(NO3)2+ KI -> PbI2+ KNO3
    • Additional Example of Double-Replacement Reactions
      Formula Equation:
      NaCl+ AgF-> NaF+ AgCl
    • Formula Equation:
      Non-Example of Double-Replacement Reaction
      1) CuCO3 -> CuO + CO2
      2) Na + Cl2 -> NaCl
    • Definition: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide.*
      Characteristics:
      A common combustion reactant is oxygen.
      Two common combustion products are carbon dioxide and water.
      Combustion Reaction
    • Additional Examples of Combustion Reaction
      Example #1:
      CH4 + O2 -> CO2+ H2O
      Example #2:
      C3H8+ O2 -> CO2 + H2O
    • Non-Example of Combustion Reaction
      1) CuCO3 -> CuO+ CO2
      2) Na + Cl -> NaCl
      3) NaCl+ AgF-> NaF+ AgCl
