  1. Today we will: Review last night’s homework Begin to work with the activity series

  2. Last Night’s Homework: Problems 14-20 on pages 285 & 286

  3. Last Night’s Homework: The solids aluminum and sulfur react to produce aluminum sulfide. Al + S2 → Al2S3

  4. Last Night’s Homework: The solids aluminum and sulfur react to produce aluminum sulfide. 4Al + 3S2 → 2Al2S3

  5. Last Night’s Homework: The solids aluminum and sulfur react to produce aluminum sulfide. 4Al + 3S2 → 2Al2S3 synthesis

  6. Last Night’s Homework: Water and dinitrogen pentoxide gas react to produce aqueous hydrogen nitrate H2O + N2O5 → HNO3

  7. Last Night’s Homework: Water and dinitrogen pentoxide gas react to produce aqueous hydrogen nitrate H2O + N2O5 → 2HNO3

  8. Last Night’s Homework: Water and dinitrogen pentoxide gas react to produce aqueous hydrogen nitrate H2O + N2O5 → 2HNO3 synthesis

  9. Last Night’s Homework: The gasses nitrogen dioxide and oxygen react to produce dinitrogen pentoxide gas NO2 + O2 → N2O5

  10. Last Night’s Homework: The gasses nitrogen dioxide and oxygen react to produce dinitrogen pentoxide gas 4NO2 + O2 → 2N2O5

  11. Last Night’s Homework: The gasses nitrogen dioxide and oxygen react to produce dinitrogen pentoxide gas 4NO2 + O2 → 2N2O5 synthesis…

  12. Last Night’s Homework: The gasses nitrogen dioxide and oxygen react to produce dinitrogen pentoxide gas 4NO2 + O2 → 2N2O5 synthesis… and combustion

  13. Last Night’s Homework: Ethane gas (C2H6) burns in air, producing carbon dioxide gas and water vapor. C2H6 + O2 → CO2 + H2O

  14. Last Night’s Homework: Ethane gas (C2H6) burns in air, producing carbon dioxide gas and water vapor. 2C2H6 + 7O2 → 4CO2 + 6H2O

  15. Last Night’s Homework: Ethane gas (C2H6) burns in air, producing carbon dioxide gas and water vapor. 2C2H6 + 7O2 → 4CO2 + 6H2O synthesis…

  16. Last Night’s Homework: Ethane gas (C2H6) burns in air, producing carbon dioxide gas and water vapor. 2C2H6 + 7O2 → 4CO2 + 6H2O synthesis… and combustion

  17. Last Night’s Homework: Aluminum oxide(s) decomposes when electricity is passed through it. Al2O3 → Al + O2

  18. Last Night’s Homework: Aluminum oxide(s) decomposes when electricity is passed through it. 2Al2O3 → 4Al + 3O2

  19. Last Night’s Homework: Nickel(II) hydroxide(s) decomposes to produce nickel(II) oxide and water Ni(OH)2 → NiO + H2O

  20. Last Night’s Homework: Nickel(II) hydroxide(s) decomposes to produce nickel(II) oxide and water Ni(OH)2 → NiO + H2O This one is already balanced.

  21. Last Night’s Homework: Heating sodium hydrogen carbonate(s) produces sodium carbonate(aq), carbon dioxide(g) and water. NaHCO3 → Na2CO3 + CO2 + H2O

  22. Last Night’s Homework: Heating sodium hydrogen carbonate(s) produces sodium carbonate(aq), carbon dioxide(g) and water. 2NaHCO3 → Na2CO3 + CO2 + H2O

  23. Tonight’s Homework: Problems 21-26 on pages 289 & 291

  24. Tonight’s Homework: Fe(s) + CuSO4(aq) → Will they react at all?
