  1. Chemical Reaction parts are mixed together to make something new

  2. Types of Reactions • Synthesis reactions • Decomposition reactions • Single displacement reactions • Double displacement reactions You need to be able to identify each type.

  3. C C + O O O O 1. Synthesis Example C + O2 General: A + B  AB

  4. Ex. Synthesis Reaction

  5. Synthesis • Predict the products. Na(s) + Cl2(g)  Mg(s) + F2(g)  Al(s) + F2(g)  2 2 NaCl(s) MgF2(s) 2 3 2 AlF3(s) Synthesis = join together

  6. + Na Na Cl Cl 2. Decomposition Example: NaCl General: AB  A + B

  7. Ex. Decomposition Reaction

  8. Decomposition • Predict the products. HgO  2KClO3 2 Hg2 + O2 2KCl + 3O2 Decomposition = split apart

  9. + +  Cl Cl Cl Cl Zn Zn Cu Cu 3. Single Displacement Example: Zn + CuCl2 General: AB + C  AC + B

  10. Ex. Single Replacement Reaction

  11. Single Replacement Reactions • Predict the products. Cl2 + 2NaBr  2NaCl + Br2 C A B A C B 2HgO + Cl2 2HgCl + O2

  12. Ca Ca  + + Mg Mg S S O O 4. Double displacement Example: MgO + CaS General: AB + CD  AD + CB

  13. Single Replacement Reactions • Predict the products. CuCl2 + H2S  CuS + 2HCl BaCl2 + Na2SO4 2NaCl + BaSO4

  14. Synthesis Decomposition join together A + B  AB split apart AB  A + B Single Replacement Double Replacement trade 1 place AB + C  AC + B trade 2 places AB + CD  AC + BD

  15. Which type of reaction? 4 P + 5 O2 P4O10 Synthesis

  16. Which type of reaction? Cl2 + 2NaBr  2NaCl + O2 Single Replacement

  17. Which type of reaction? BaCl2 + Na2SO4 2NaCl + BaSO4 Double Replacement

  18. Which type of reaction? 2 HgO + Cl2 2HgCl + O2 Single Replacement

  19. Which type of reaction? 2 Al2O3 4 Al + 3 O2 Decomposition

  20. Which type of reaction? CuCl2 + H2S  CuS + 2HCl Double Replacement

  21. Which type of reaction? 3 H2 + N2 2 NH3 Synthesis

  22. Which type of reaction? 2 HgO  2Hg + O2 Decomposition
