  1. Predicting Products of Chm Rxns

  2. Synthesis

  3. Synthesis • M + X MaXb

  4. Synthesis • MO + CO2 Ma(CO3)b

  5. Synthesis • MO + SO2 Ma(SO3)b

  6. Decomposition

  7. Heating metal carbonates Mx(CO3)y MxOy + CO2

  8. Heating metal bicarbonates M(HCO3)y MO + H2O + CO2

  9. Heating ammonium carbonate (NH4)2CO3 NH3 + H2O + CO2

  10. Heating metal chlorates M(ClO3)y MCly + O2

  11. Heating metal nitrates M(NO3)y M(NO2)y + O2

  12. Active metals in water (SR) M + H2O M(OH)y + H2

  13. Active metal oxides in water MxOy + H2O M(OH)y

  14. Nonmetals oxide in water XOn + H2O HzXOm

  15. Single Displacement MaXb + Yc MaYb + Xc

  16. Single Displacement MaXb + A AaXb + M

  17. Double Displacement MaXb + AcYd MeYf + AgXh

  18. Combustion CxHyOz add O2 CO2 + H2O

  19. REDOX

  20. REDOX • Acidified or basified X plus ox or red agent

  21. Oxidizing Agents MnO4-1 Cr2O7-2

  22. Reducing Agents Column I & II CO

  23. Oxidation • The ox # of something goes up while the ox # of the oxidizing agent goes down, then balance

  24. Reduction • The ox # of something goes down while the ox # of the reducing agent goes up, then balance

  25. Dehydrating Agent Heat & H2SO4

  26. Dehydration • Remove water

  27. Acid/Base HA + MOH MA + HOH

  28. Complex Ions Positive Metal ion plus: Cl-SCN- CN- NH3 OCN-
