  1. Today we will: Review homework Talk about upcoming test Talk about tomorrow’s lab Look at our grades

  2. Last Week’s Homework: Problems 21-26 on pages 289 & 291

  3. Last Week’s Homework: Predict if the following single-replacement reactions will occur. If a reaction occurs, write a balanced equation for the reaction.

  4. Last Week’s Homework: 21. K + ZnCl2 →

  5. Last Week’s Homework: 21. K + ZnCl2 → KCl + Zn

  6. Last Week’s Homework: 21. 2K + ZnCl2 → 2KCl + Zn

  7. Last Week’s Homework: 22. Cl2(g) + HF(aq) →

  8. Last Week’s Homework: 22. Cl2(g) + HF(aq) → no reaction

  9. Last Week’s Homework: 23. Fe(s) + Na3PO4(aq) →

  10. Last Week’s Homework: 23. Fe(s) + Na3PO4(aq) → no reaction

  11. Last Week’s Homework: Lithium iodide and silver nitrate produce silver iodide and lithium nitrate

  12. Last Week’s Homework: Lithium iodide and silver nitrate produce silver iodide and lithium nitrate LiI + AgNO3 → AgI + LiNO3

  13. Last Week’s Homework: Lithium iodide and silver nitrate produce silver iodide and lithium nitrate LiI + AgNO3 → AgI + LiNO3 already balanced

  14. Last Week’s Homework: 25. Barium chloride and potassium carbonate produce barium carbonate and potassium chloride

  15. Last Week’s Homework: 25. Barium chloride and potassium carbonate produce barium carbonate and potassium chloride BaCl2 + K2CO3 → BaCO3 + KCl

  16. Last Week’s Homework: 25. Barium chloride and potassium carbonate produce barium carbonate and potassium chloride BaCl2 + K2CO3 → BaCO3 + 2KCl

  17. Last Week’s Homework: 26. Sodium oxalate and lead(II) nitrate produce lead(II) oxalate and sodium nitrate

  18. Last Week’s Homework: 26. Sodium oxalate and lead(II) nitrate produce lead(II) oxalate and sodium nitrate Na2C2O4 + Pb(NO3)2 → PbC2O4 + NaNO3

  19. Last Week’s Homework: 26. Sodium oxalate and lead(II) nitrate produce lead(II) oxalate and sodium nitrate Na2C2O4 + Pb(NO3)2 → PbC2O4 + 2NaNO3
