  1. Twenty Questions Chemical Reactions

  2. Twenty Questions

  3. 1. When two or more substances combine to form one compound • Synthesis Reaction

  4. 2. What is the solid that comes out of a solution called? • Precipitate

  5. 3. What is an ion that does not participate in a reaction called? • Spectator ion

  6. 4. An equation that only contains those substances directly involved in reactions • Net ionic equation

  7. 5. Balance the following equation__K + __MgBr2 → __KBr + ___Mg • 2K + MgBr2 → 2KBr + Mg

  8. 6. Balance the following equation:_AlBr3 + _K2SO4 →_ KBr + _Al2(SO4)3 • 2AlBr3 + 3K2SO4 → 6KBr + Al2(SO4)3

  9. 7. Balance the following equation:_ C6H12O6 + _O2 → _ CO2 + _H2O • C6H12O6 + 6O2 → 6CO2 + 6H2O

  10. 8. Is AgC2H3O2 soluble or insoluble; what rule supports your answer? • Soluble, Rule 3 says acetate ions are soluble

  11. 9. Is Be(ClO3)2 soluble or insoluble; what rule supports your answer? • Be(ClO3)2 is soluble, Rule 7 says chlorates are soluble

  12. 10. Is Mg3(PO4)2 soluble or insoluble; what rule supports your answer? • Mg3(PO4)2 insoluble. It breaks all 9 rules.

  13. 11. Predict the products for the following reaction, don’t balance:Ag(s) + CuCl2(aq)  ? • No reaction occurs. Ag has a lower activity that Cu and can’t replace it.

  14. 12. Predict the products for the following reaction, don’t balance:Fe(NO3)2(aq) + Al(s)  • Fe(NO3)2(aq) + Al(s)  Fe(s) + AlNO3(aq)

  15. 13. Predict the products for the following reaction, don’t balance:An aqueous solution of sodium carbonate is reacted with an aqueous solution of calcium chloride • Na2CO3 (aq) + CaCl2 (aq) → • Na2CO3 (aq) + CaCl2 (aq) → NaCl (aq) + CaCO3 (s)

  16. 14. Predict the products for the following reaction, don’t balance:Fe(NO3)2(aq) + Al(s)  • Fe(NO3)2(aq) + Al(s)  Al(NO3)3 (aq)+ Fe(s)

  17. 15. Write the complete ionic equation for:2AgNO3 (aq)+ BaSO4 (aq)  Ag2SO4(s) + Ba(NO3)2(aq) • 2Ag+ + 2NO3-+ Ba2+ + SO42- Ag2SO4(s) + Ba2+ + (NO3)2 -

  18. 16. Write the net ionic equation for the following:2Ag+ + 2NO3-+ Ba2+ + SO42- Ag2SO4(s) + Ba2+ + (NO3)2 - • 2Ag+ + SO42- Ag2SO4(s)

  19. 17. Put the following metals in order from least reactive to most reactive: Li, Au, Ca, K, Zn, Cr • Au, Cr, Zn. Ca, K, Li

  20. 18. What type of equation is the following: Al2(SO4)3 + 2Na3PO4 → 3Na2SO4 + 2AlPO4 • Double Replacement
