types of reactions

• Types of reactions


  • Combination/synthesis
  • Decomposition
  • Displacement
  • Double decomposition/Ionic precipitation
  • Reversible
  • Neutralisation
  • Redox
• Combination/synthesis reactions


  Reactions where two or more reactants react to produce one product
• Decomposition reactions


  Reactions where one reactant breaks down into two or more products
• Displacement reactions


  One compound is replaced by another element or group
• Reactivity of metals


  • K
  • Na
  • Ca
  • Mg
  • Al
  • Zn
  • Fe
  • Pb
  • H
  • Cu
  • Hg
  • Ag
  • Au
• Reactivity of non-metals


  • F
  • Cl
  • Br
  • I
• Double decomposition/Ionic precipitation


  Reactants are aqueous (two solutions), one product is aqueous and the other is a solid
• Reversible reactions


  The reaction can proceed from reactants to products and products to reactants
• Neutralisation reactions


  Acid + Base -> Salt + Water
• Redox reactions


  Reactions where oxidation and reduction occurs (elements to ions, ions to elements or compounds, charges on ions are changing)
