  1. Warm-up Balance the following equations: Ba(OH)2 + HCl  BaCl2 + H2O LiClO3  LiCl + O2 C6H14 + O2  H2O + CO2

  2. Types of Reactions

  3. A. Combustion • Hydrocarbon + oxygen  carbon dioxide and water • CH4 + 2O2  CO2 + 2H2O • 2C8H18 + 25O2  16CO2 + 18H2O

  4. Synthesis • the combination of 2 or more substances to form a compound • only one product A + B  AB

  5. Synthesis H2(g) + Cl2(g)  2 HCl(g)

  6. Decomposition • a compound breaks down into 2 or more simpler substances • only one reactant AB  A + B

  7. Decomposition 2 H2O(l)  2 H2(g) + O2(g)

  8. Single Replacement • one element replaces another in a compound • metal replaces metal (+) • nonmetal replaces nonmetal (-) A + BC  B + AC

  9. Single Replacement Cu(s) + 2AgNO3(aq)  Cu(NO3)2(aq) + 2Ag(s)

  10. Double Replacement • ions in two compounds “change partners” • cation of one compound combines with anion of the other AB + CD  AD + CB

  11. Double Replacement Pb(NO3)2(aq) + K2CrO4(aq)  PbCrO4(s) + 2KNO3(aq)
