Balancing Chemical Equations

  1. 1. Do Now Activity- For Collection<br />Utilizing the following chemical reaction, identify and list in separate columns the reactants and products, Balance the equation and calculate the molar mass of each compound<br />Al(s) + NH4ClO4(s) Al2O3(s) + AlCl3(s) + NO(g)+ H2O(g)<br />3<br />1<br />3<br />3<br />1<br />6<br />
  2. 2. Al(s) + NH4ClO4(s) Al2O3(s) + AlCl3(s) + NO(g)+ H2O(g)<br />Reactants<br />Al<br />NH4ClO4<br />Products<br />Al2O3<br />AlCl3<br />NO<br />H2O<br />
  3. 3. Al(s) + NH4ClO4(s) Al2O3(s) + AlCl3(s) + NO(g)+ H2O(g)<br />Al: 27 g/mole<br />NH4ClO4: 117 g/mole<br />Al2O3: 102 g/mole<br />AlCl3: 132 g/mole<br />NO: 30 g/mole<br />H2O: 18 g/mole<br />

  5. 5. Homework Worksheet #32<br />Balancing Chemical Equations<br />
  6. 6. Na2CO3 CO2 + Na2O<br />Balanced<br />Decomposition<br />
  7. 7. Cu+LiOH NR<br />Trying to be …. <br />Why no reaction(NR)<br />See Activity Series Chart (Go To Chart)<br />Single replacement Rxn<br />
  8. 8. NaOH+Fe(NO3)2-> Fe(OH)2 + NaNO3<br />Double Replacement<br />Not Balanced<br />2NaOH+Fe(NO3)2-> Fe(OH)2 + 2NaNO3<br />
  9. 9. Be+O2-> BeO<br />Combination<br />Not Balanced<br />2Be+O2-> 2BeO<br />
  10. 10. OF2-> O2 + F2<br />Decomposition<br />Not Balanced<br />2OF2-> O2 +2F2<br />
  11. 11. Al+CuSO4-> Al2(SO4)3 + Cu<br />Single Replacement<br />Not Balanced<br /> 2Al+3CuSO4-> Al2(SO4)3 + 3Cu<br />
  12. 12. Sr+I2-> SrI2<br />Combination<br />Balanced<br />
  13. 13. C3H6+O2-> CO2 + H2O<br />Combustion<br />Not Balanced<br />2C3H6+ 9O2-> 6CO2+ 6H2O<br />
  14. 14. CdBr2+Na2S-> CdS + NaBR<br />Double Replacement Reaction<br />Not Balanced<br />CdBr2+Na2S-> CdS + 2NaBR<br />
  15. 15. Atom Inventory<br />Breaking down a compound into its parts and counting how many of each part you have.<br />Useful for calculating Molar Mass and determining a balanced chemical equation.<br />
