TYPES OF CHEMICAL REACTION

• Chemical Reaction


  A process in which one or more substances are converted to one or more different substances
• Chemical Equation


  A symbolic representation of a chemical reaction
• Components of a Chemical Equation

  • Reactants (substances before the reaction)
  • Products (substances resulting from the reaction, new substance formed)
• Types of Chemical Reactions

  • Combination or Synthesis Reactions (two or more elements/compounds combine to form a single larger compound)
• Combination or Synthesis Reactions

  • Mg + O2 → MgO
• Decomposition Reactions

  • 2Na + I2 → 2NaI
• Single Displacement Reactions

  • CaCl2 + 2Na → 2NaCl + Ca
• Double Displacement Reactions

  • Pb(NO3)2 + 2KI → 2KNO3 + PbI2
• Combustion Reactions (complete)

  • CH4 + 2O2 → CO2 + 2H2O
• Combustion Reactions (incomplete)

  • C4H10 + 5O2 → CO2 + CO + C + 5H2O
• • Combination or Synthesis Reactions (two or more elements/compounds combine to form a single larger compound)
• • Single Displacement Reactions (one element displaces another element in a compound)
• • Double Displacement Reactions (elements in different compounds exchange places to form two new compounds)
• • Combustion Reactions (rapid reaction of a hydrocarbon with oxygen)
• • Acid-base or Neutralization Reactions (a double displacement reaction when an acid or base reacts to produce salt and water)
