    Synthesis Reactions

    Definition: 2 or more substances react to form 1 substance

    General Equation for a synthesis reaction:

                       A + B > AB

    The product made is always a _______________!

    Example of a synthesis reaction:

             2Na + Cl2 > 2NaCl

    Decomposition ReactionsDefinition: a compound breaks down into 2 or more simpler substances

    General Equation for a decomposition reaction:

    AB > A  +  B

    The reactant is always a ___________________!

    Example of a decomposition reaction:           H2CO3 > CO2  +  H2O

    Single Replacement Reactions

    Definition: 1 element switches places with another in a compound.

    General Equation for a SingleReplacement Reaction:

    A + BC  >  B + AC

    Example of a SingleReplacement Reaction:

    Cu  +  2AgNO3  >  Cu(NO3)2  +  2Ag

    Copper (Cu) replaced silver (Ag)

    DoubleReplacement Reactions

    Definition: compounds exchange ions to form 2 new compounds

    General Equation for a DoubleReplacement Reaction:

    AB  +  CD  >  AD  +  CB

    Example of a DoubleReplacement Reaction:

    CaCO3  +  2HCl  >  CaCl2  +  H2CO3

    Calcium and hydrogen switch places.

    Combustion Reactions

    Definition: substances reacting with oxygen

    Example of a Combustion Reaction:

    CH4  +  2O2  >  CO2  +  2H2O

    OxidationReduction Reactions

    Definition: reactions in which electrons are transferred from one reactant to another.

    Oxidation: when an atom loses an electron

    Reduction: when an atom gains an electron

    *Oxidation and reduction always occur together!

    Example of an OxidationReduction reaction:

    2Ca +  O2  >  2Ca2+O2

    Which atom has been oxidized?

    Which atom has been reduced?

    Dec 1412:28 PM

    a type of chemical process typified by the exchange of one or more hydrogen ions, H+, between species that may be neutral (molecules, such as water, H2O; or acetic acid, CH3CO2H) or electrically charged (ions, such as ammonium, NH4+; hydroxide, OH−; or carbonate, CO2/3−).
