Types of Chemical Reactions

Synthesis Two or more elements or compounds combined to make one compound. A + B  AB H 2 + O 2  H 2 O M4z74

Decomposition (Analysis) One compound broken down into two or more substances EF  E + F (NH4)2Cr2O7  Cr2O3 + N2 + H2O 1X7Gg

Single Replacement Element combined with a compound to form a new element and a different compound. DE + F  DF + E or XY + Z  ZY + X Na + H2O  NaOH + H 2

Double Replacement (Ion Exchange or Precipitation) Two compounds react to form two new compounds ST + MP  MT + SP KI + Pb(NO3)2  PbI2 + KNO3

Oxidation-Reduction Electrons are transferred from one element to another. One element loses electrons (oxidation) and another element gains electrons (reduction) B&view=detail&FORM=VIRE4&adlt=strict (Bioluminescence)

Combustion Organic compound is rapidly reacted with oxygen
