Balancing Equations

  1. 1. Synthesis, Decomposition, Single, or Double Replacement? 1. N2 + 3H2 2NH3 1. Synthesis 2. 2Br2 + 2H2O  4HBr + O2 2. Singe Replacement 3. 2KBr + H2SO4  K2SO4 + 2HBr 3. Double Replacement 4. 4. H2SO3  H2O + SO2 Decomposition
  2. 2. Review Types of chemical reactions: Synthesis Decomposition Replacement: single and double
  3. 3. Balancing Equations Balanced equation- correct coefficients in place so the same numbers of, and types of, atoms appear on both sides of the equation
  4. 4. Balancing Equations  2H2 + (1)O2  2(H2O(1)) 4 hydrogen's + 2 oxygen's  2 water molecules
  5. 5. Balancing Equations 2H2 + (1)O2  2(H2O(1)) 4 H’s on the left and right 2 O’s on the left and right
  6. 6. Balancing Equations 2H2 + O2  2H2O  Only change coefficients- big numbers in front of equations  Not subscripts- little numbers after equations
  7. 7. Zn + HCl  ZnCl2 + H2
  8. 8. K + H 2O  KOH + H2
  9. 9. H 2O 2 + PbS  PbSO4 + H 2O
  10. 10. Mg + H 2O  Mg(OH)2 + H2
  11. 11. H2 + H2O2 Na O2  H2O  + O2 H2O  + Na2O O2
  12. 12. N2 + H2 P4 + O2 C + H2  NH3  P4O6  CH4
  13. 13. Al2O3  Fe + H2O Al +  O2 Fe3O4 + H2
  14. 14. C2 H6 + O 2  CO2 + H2O
  15. 15. Na2SO4 + CaCl2 CaSO4 + NaCl
