  1. Types of Chemical Reactions

  2. Combustion • Exothermic reaction where a substance (usually a hydrocarbon) combines with oxygen • Products are carbon dioxide and water (and light & heat)

  3. Synthesis • Two or more substances react to form ONE product • One of the products formed is larger or more complex than any of the reactants • General Form: • A + B → AB • “Chemical Dance” Example

  4. Examples of Synthesis Reactions • Producing Ammonia (Haber Process): • N2(g) + 3 H2(g) → 2 NH3(g) • Producing Water • 2 H2(g) + O2(g) → 2 H2O(l) • Rusting of Iron • 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) • “Green” Statue of Liberty • 2 Cu + O2 2 CuO

  5. Decomposition • The reactant compound is broken down into two or more simpler substances • General Form: • AB → A + B • “Chemical Dance” • Examples: • H2CO3(aq) H2O(l) + CO2(g) • Electrolysis of water

  6. Decomposition of Water by Electrolysis

  7. Single Replacement • One element replaces another element in a compound • General Form: • A + BC → B + AC • “Chemical Dance” • Examples: • 2 AgNO3(aq) + Cu(s) • Cu(NO3)2(aq) + 2 Ag

  8. Double Replacement • Two elements in different compounds exchange places • General Form: • AB + CD → AD + CB • “Chemical Dance” • Examples: • 2 KI(aq) + Pb(NO3)2(aq) 2 KNO3(aq) + PbI2(s) • CaCO3 + 2 HCl → CaCl2 + H2CO3
