  1. Chemical Reactions

  2. In each of the following slides, a reaction we have done in class is named. The type of reaction, the reaction in words, the equation, and the balancedequation are shown. Try, as you go along, to predict the next step

  3. Synthesis Magnesium and oxygen produce magnesium oxide Mg + O2 MgO 2MgO 2Mg + O2

  4. Decomposition Hydrogen peroxide breaks down into water and oxygen H2O2 + H2O O2 O2 2H2O2 + 2H2O2

  5. Single replacement Aluminum and hydrochloric acid produce aluminum chloride and hydrogen gas Al + HCl AlCl3 + H2 2Al + 6HCl 2AlCl3 + 3H2

  6. Double Replacement Lead nitrate and sodium iodide produce sodium nitrate and lead iodide NaNO3 + PbI2 Pb(NO3)2 + NaI PbI2 Pb(NO3)2 + 2NaI 2NaNO3 +

  7. Synthesis Iron(III) and oxygen produce iron oxide (rust) Fe2O3 Fe(III) + O2 4Fe(III) + 3O2 2Fe2O3

  8. Single replacement Iron and copper sulfate produce iron sulfate and copper FeSO4 + Cu Fe + CuSO4 Balanced!

  9. Double replacement and decomposition Sodium bicarbonate and acetic acid produce sodium acetate, carbon dioxide, and water NaHCO3 + C2H4O2 NaC2H3O2 + CO2 + H2O Balanced !

  10. Now let’s try some more. Balance the equation, and tell what type of reaction is shown.

  11. H2O H2 + O2 2H2 + O2 2H2O Decomposition

  12. N2 + H2 NH3 N2 + 3H3 2NH3 Synthesis

  13. CO2 + H2O C3H8 + O2 3CO2 + H2O C3H8 + 5O2 Single replacement

  14. H2 + KOH K + H2O 2K + 2H2O H2 + 2KOH Single replacement

  15. Li + O2 Li2O 2Li2O 4Li + O2 Synthesis

  16. Ag + N2 Ag3N 6Ag + N2 2Ag3N Synthesis

  17. C2H5OH + O2 CO2 + H2O C2H5OH + 3O2 2CO2 + 3H2O Decomposition

  18. The End !
