  1. Types of Chemical Reactions

  2. What you will know after the next two class periods • You will be able to identify a combustion reaction • You will be able to identify a double replacement reaction • You will be able to identify a single replacement reaction • You will be able to identify a synthesis reaction • You will be able to identify a decomposition reaction • You will be able to balance all of these chemical reactions • You will have a greater appreciation for the power of some simple chemicals

  3. 5 Major Rxn Types 5 types of reactions

  4. Some type of hydrocarbon (fuel) + O2 ------> CO2 + H2O + heat Combustion Reaction  C3H8O(l) + O2(g) -------> CO2(g) + H2O(l) + heat Isopropyl alcohol  2 C3H8O(l) + 9 O2(g) -------> 6 CO2(g) + 8 H2O(l) 1 mole of IPA 60 g Molar mass = 60 g/mol

  5. AB + CD ------> AD + CB Double Replacement Reaction Pb(NO3)2(aq) + KI(aq) -------> PbI2(s) + KNO3(aq) Pb(NO3)2(aq) + 2 KI(aq) -------> PbI2(s) + 2 KNO3(aq)

  6. A + BC ------> AC + B Single Replacement Reaction (Displacement Rxn) Zn(s) + HCl(aq) -------> ZnCl2(aq) + H2(g) + heat Zn(s) + 2 HCl(aq) -------> ZnCl2(aq) + H2(g) + heat

  7. A (metal) + BC ------> AC + B How Can We Tell If A Single Replacement Reaction Will Occur? Zn(s) + 2 HCl(aq) -------> ZnCl2(g) + H2(g) Table similar to this on page 333 of your textbook

  8. A + B ------> AB Synthesis Reaction  H2(g) + O2(g) -------> H2O(g) + lots of heat  2H2(g) + O2(g) -------> 2H2O(g) + lots of heat

  9. AB ------> A + B Decomposition Reaction ABC ------> AB + C ABC ------> A + B + C

  10. Decomposition Reaction

  11. Decomposition Reaction “The Catalyst” Yogi

  12. AB ------> A + B Decomposition Reaction ABC ------> AB + C  KClO3(s) ------> KCl(s) + O2(g)  2 KClO3(s) ------> 2 KCl(s) + 3 O2(g)
