  1. Balancing Reactions

  2. Balancing Reactions • Choose the largest compound • Make its coefficient 1 • Choose any element in that compound that appears in only 1 other location

  3. Balance that element with coefficients where that element appears • Repeat until all elements are balanced • Double if on half-unit

  4. _ MnBr3(aq) + _ F2(g) •  • _ MnF3(aq) + _ Br2(g)

  5. 2 MnBr3(aq) + 3 F2(g) •  • 2 MnF3(aq) + 3 Br2(g)

  6. _ FeCl3 + _ K2CO3 •  • _ Fe2(CO3)3 + _ KCl

  7. _NaHCO3 + Heat •  • _Na2CO3 + _H2O + _CO2

  8. Drill: Balance Rxn __ Fe(NO3)3 + __ K2SO4 __ Fe2(SO4)3 + __ KNO3

  9. __H3PO4 + __NH3 •  • __(NH4)3PO4

  10. __C4H10O2 + __O2  __CO2 + __H2O

  11. Types of Reactions

  12. Single Displacement • Double displacement • Synthesis • Decomposition • Combustion

  13. Single Displacement • A Metal or hydrogen replaces the positive portion of a compound or a nonmetal does it for the negative portion

  14. _ CaBr2(aq) + _ F2(g) •  • _ CaF2(aq) + _ Br2(g)

  15. Double Displacement • Two compounds exchange negative portions • Change of phase a must

  16. Double Displacement __ Ca(NO3)2 + __ K2SO4 __ CaSO4 + __ KNO3

  17. Synthesis • Smaller molecules or elements combine to make larger molecules

  18. Synthesis • _CaO + _CO2 •  • _CaCO3

  19. Decomposition • Larger molecules break down to form smaller molecules or elements

  20. Decomposition • _MgCO3 + Heat •  • _MgO + _CO2

  21. Combustion • A carbon compound is combined rapidly with oxygen producing carbon dioxide & water

  22. Combustion __C5H12 + __O2  __CO2 + __H2O

  23. Name substances, then balance & classify the following reactions

  24. ___H2SO4 + ___Al(OH)3___Al2(SO4)3 + ___H2O

  25. ___K3PO4 + ___Pb(NO3)2___Pb3(PO4)2 + ___KNO3

  26. _ MnBr3(aq) + _ F2(g) •  • _ MnF3(aq) + _ Br2(g)

  27. _ FeCl3 + _ K2CO3 •  • _ Fe2(CO3)3 + _ KCl

  28. CaCO3(s) + H2O + CO2 • Ca(HCO3)2(aq)

  29. __H3PO4 + __NH3 •  • __(NH4)3PO4

  30. __C4H10O2 + __O2  __CO2 + __H2O
