Synthesis and Decomposition Reactions

  1. 1. Chemical ReactionsPredicting Products of Different Types of Reactions
  2. 2. Classifying Reactions• Synthesis Reactions (combination)• Decomposition Reactions• Single-Replacement Reactions• Double-Replacement Reactions• Combustion Reactions• Neutralization Reactions
  3. 3. Synthesis Reactions• Also called combination reactions• Two or more substances react to form a single new substance• Only 1 product in the reaction• A + B AB
  4. 4. • 2 elements react to produce a binary compound – 2Na + Cl2 2NaCl – 2Mg + O2 2MgO – S + O2 SO2• Metal oxide + water metal hydroxide – CaO + H2O Ca(OH)2• Nonmetal oxide + water oxyacid – SO3 + H2O H2SO4
  5. 5. 1. Ca + F22. N2O5 + H2O3. MgO + H2O4. Al + O25. SO3 + H2O6. K + O27. Li + N28. ZnO + H2O9. P2O5 + H2O10. K2O + H2O
  6. 6. Decomposition Reactions• A single compound breaks down into two or more simpler products• AB A + B• Only 1 reactant
  7. 7. • Metal chlorates metal chlorides + oxygen – 2NaClO3 2NaCl + 3O2• Metal hydroxides metal oxides + water – Mg(OH)2 MgO + H2O• Metal carbonates metal oxides + carbon dioxide – CaCO3 CaO + CO2• Oxyacids nonmetalic oxides + water – H2SO3 SO2 + H2O• Binary compounds individual elements – 2NaCl 2Na + Cl2
  8. 8. 1. CaCO32. AlCl33. H2CO34. KClO35. KOH6. MgCO37. Al(ClO3)38. Ag2O9. Fe(OH)210. Al2(CO3)3
