Synthesis Reactions

  • Formation of compounds from simpler reactants.
  • Examples include:
    • ( \text{Sb} + \text{Cl}_2 \rightarrow \text{SbCl}_3 )
    • ( \text{Mg} + \text{O}_2 \rightarrow \text{MgO} )
    • ( \text{N}_2 + \text{H}_2 \rightarrow \text{NH}_3 )
    • ( \text{Fe} + \text{O}_2 \rightarrow \text{Fe}_3\text{O}_4 )
    • ( \text{Li} + \text{O}_2 \rightarrow \text{Li}_2\text{O} )
    • ( \text{Mg} + \text{N}_2 \rightarrow \text{Mg}_3\text{N}_2 )
    • ( \text{P} + \text{O}_2 \rightarrow \text{P}_4\text{O}_6 )
    • ( \text{Sn} + \text{Cl}_2 \rightarrow \text{SnCl}_4 )

Decomposition Reactions

  • Breakdown of compounds into simpler substances.
  • Examples include:
    • ( \text{CaCl}_2 \rightarrow \text{Ca} + \text{Cl}_2 )
    • ( \text{HgO} \rightarrow \text{Hg} + \text{O}_2 )
    • ( \text{KClO}_3 \rightarrow \text{KCl} + \text{O}_2 )

    • ( \text{MgCO}_3 \rightarrow \text{MgO} + \text{CO}_2 )
    • ( \text{H}_2\text{O} \rightarrow \text{H}_2 + \text{O}_2 )
    • ( \text{NH}_4\text{NO}_2 \rightarrow \text{N}_2 + \text{H}_2\text{O} )

Single Replacement Reactions

  • One element replaces another in a compound.
  • Examples include:
    • ( \text{Fe} + \text{HCl} \rightarrow \text{FeCl}_2 + \text{H}_2 )
    • ( \text{CuO} + \text{H}_2 \rightarrow \text{Cu} + \text{H}_2\text{O} )
    • ( \text{Al} + \text{H}_2\text{SO}_4 \rightarrow \text{Al}_2(\text{SO}_4)_3 + \text{H}_2 )
    • ( \text{KBr} + \text{Cl}_2 \rightarrow \text{KCl} + \text{Br}_2 )
    • ( \text{Zn} + \text{AgNO}_3 \rightarrow \text{Zn(NO}_3)_2 + \text{Ag} )
    • ( \text{SnO}_2 + \text{C} \rightarrow \text{Sn} + \text{CO} )
    • ( \text{Fe}_3\text{O}_4 + \text{H}_2 \rightarrow \text{Fe} + \text{H}_2\text{O} )

Double Replacement Reactions

  • Exchange of ions between two compounds.
  • Examples include:
    • ( \text{Pb(NO}_3)_2 + \text{H}_2\text{S} \rightarrow \text{PbS} + \text{HNO}_3 )
    • ( \text{Mg(OH)}_2 + \text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2\text{O} )
    • ( \text{Na}_2\text{CO}_3 + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2\text{CO}_3 )
    • ( \text{SrBr}_2 + (NH_4)_2\text{CO}_3 \rightarrow \text{SrCO}_3 + \text{NH}_4\text{Br} )
    • ( \text{AgNO}_3 + (NH_4)_2\text{CrO}_4 \rightarrow \text{Ag}_2\text{CrO}_4 + \text{NH}_4\text{NO}_3 )
    • ( \text{ZnCl}_2 + \text{KOH} \rightarrow \text{Zn(OH)}_2 + \text{KCl} )
