Types of Chemical Reactions

Ashy Willyson

Synthesis Reaction

  • A synthesis reaction is a type of reaction in which multiple reactants combine to form a single product.
  • A+B--->AB
  • Mg + O2 ---> MgO
H2 + O2 ---> H2O

K + Cl2 ---> KCl

Decomposition

  • Decomposition is when one compound splits apart into two or more elements or compounds.
  • AB---> A+B
  • HgO ---> Hg + O2
    H2O ---> H2 + O2
    MgCl2 ---> Mg + Cl2

Single-Replacement Reaction

  • During single-replacement, one element replaces another element in a compound.
  • AX + Y ---> YX + A
  • Cu + AgNO3 ---> Ag + Cu(NO3)2
    Fe + Cu(NO3)2 ---> Fe(NO3)2 + Cu
    Ca + H2O ---> Ca(OH)2 + H2

Double-Replacement Reaction

  • During Double Replacement, he cations and anions of two different compounds switch places.
  • AB+XY--->AY+XB
  • KOH + H2SO4 ---> K2SO4 + H2O
    FeS + HCl ---> FeCl2 + H2S
    NaCl + H2SO4 ---> Na2SO4 + HCl

Combustion

  • Combustion is the reaction of oxygen gas with anything.
  • CxHy + O2 ---> CO2 + H2O
  • CH4 + O2 ---> CO2 + H2O
    C2H6 + O2 ---> CO2 + H2O
    C6H12O6 + O2 ---> CO2 + H2O
