  1. Chemical Reaction Types

  2. We will study these five general types of reactions: synthesis decomposition single displacement double displacement combustion. Once you know these reaction types, you will be able to look at the reactants of a reaction and predict what products will be formed. Chemical reaction types

  3. The general form is: element + element compound 2Na + Cl2→ 2NaCl 4Fe + 3O2→ 2Fe2O3

  4. More Examples: 2H2 + O2 2H2O 4Al + 3O2 2Al2O3 Ca + Cl2 CaCl2 SYNTHESIS

  5. The general form is: Compound  element + element 2H2O → 2H2 + O2 H2CO3→ H2O + CO2

  6. More Examples: 2HgO  2Hg + O2 2KClO3 2KCl+ 3O2 DECOMPOSITION

  7. The general form is: element + compound compound + element • Zn + 2HCl  ZnCl2 + H2 • 2Na + 2H2O  2NaOH + H2

  8. More Examples: Zn + Cu(NO3)2 Cu + Zn(NO3)2 Cu + 2 AgNO3 2Ag + Cu(NO3)2 Mg + 2HCl  H2 + MgCl2 SINGLE REPLACEMENT

  9. The general form is: compound + compound  compound + compound • MgCO3 + 2HCl  MgCl2 + H2CO3 • 2KCl + Pb(NO3)2 2KNO3 + PbCl2

  10. More Examples: AgNO3 + NaCl  AgCl + NaNO3 NaOH + HCl  NaCl + H2O Ba(NO3)2 + Na2SO4 BaSO4 + 2NaNO3 DOUBLE REPLACEMENT

  11. The general form is: hydrocarbon + oxygen  carbon dioxide + water • CH4 + 2O2  CO2 + 2H2O • C7H16 + 11O2 7CO2 + 8H2O

  12. Example: 2CH4 + 4O2 2CO2 + 4 H2O COMPLETE COMBUSTION
