302 Balancing CHEM RXNs:
  • Write all answers in your bound journal
  • Make it NEAT and in COMPLETE SENTENCES, clearly identify which section you are working (using numbers)
  • Box final answers if doing math.
  • -2pt if you do not title and date the entry
  • -1pt (per infraction) if you do not clearly identify the sections, or number the problems

 

For 1-6:

  • Write out each chemical equation using words
  • Then write out each chemical equation using formulas (what is given)
  • Balance the equation
  • Then name the type of reaction

 

  1. ____ NaBr + ____ Ca(OH)2 --> ___ CaBr2 + ____ NaOH
    Type of reaction: _____________________________

     
  2. ____ NH3+ ____ H2SO4 --> ____ (NH4)2SO4
    Type of reaction: _____________________________

     
  3. ____ C5H9O + ____ O2 --> ____ CO2 + ____ H2O
    Type of reaction: _____________________________

     
  4. ____ Pb + ____ H3PO4 --> ____ H2 + ____ Pb3(PO4)2
    Type of reaction: _____________________________

     
  5. ____ Li3N + ____ NH4NO3 --> ___ LiNO3 + ___ (NH4)3N
    Type of reaction: _____________________________

     
  6. ____ HBr + ___ Al(OH)3 --> ___ H2O + ___ AlBr3
    Type of reaction: _____________________________

 

For 7-12: Using the name for the type of chemical reaction (in Parenthesis):

  • Write out each chemical equation using words
  • Then write out each chemical equation using formulas
  • Finally balance the equation
