Presentation Transcript

  1. Chapter 8 • Chemical Equation • Indicators of a reaction • Energy (heat or light) • Gas (effervescence) • Precipitation (solid forms)

  2. Word Equations • Zinc plus hydrochloric acid yields hydrogen and zinc II chloride • Formula Equations • Zn + HCl  H2 + ZnCl2 • Coefficients • 2H2 (g) + O2 (g) <-- ---> 2H2O (l)

  3. Other symbols • (s) (l) (g) • (ppt) • (aq) • ∆ • Information from a reaction • 2H2 (g) + O2 (g) <-- ---> 2H2O (l)

  4. Balancing Reactions • Make sure atoms on both sides are equal • S + O2 --> SO • 2S + O2 --> 2SO • Some times you have to get creative

  5. C2H6 + O2 --> CO2 + H2O • C2H6 + O2 --> 2 CO2 + H2O • C2H6 + O2 --> 2 CO2 + 3 H2O • C2H6 + 7/2 O2 --> 2 CO2 + 3 H2O • Multiply all by 2 • 2 C2H6 + 7 O2 --> 4 CO2 + 6 H2O

  6. Types of reactions • Synthesis • S + O2 --> SO2 • Decomposition • CO2 --> CO + O2

  7. Single - Replacement • NaCl + Br2 --> NaBr + Cl2 • Double - Replacement • KI + MgO --> MgI2 + K2O • Combustion • CH4 + O2 --> CO2 + H2O

  8. Type of reaction? • NaI + Br2 NaBr + I2 • KOH + HCl  H2O + KCl • Mg + O2  MgO • C2H6 + O2  CO2 + H2O

  9. CH4 + O2 • LiCl + F2  • HCl + NaOH  • KI  • Ca + I2 

  10. C + S8 CS2 • C6H12O6  C + H2O • Zn + HNO3  Zn(NO3) 2 + H2 • FeCl3 + H2O  Fe(OH)3 + HCl

  11. Activity Series • Metals • Nonmetals • Table 8-3 pg 266
