                                    Classifying Chemical Reactions Lab

Objectives:
             perform and classify six different reactions
             identify the reactants and products of each reaction
             write and balance equations for each reaction

Materials: Materials will be provided for you at each station. You MUST wear goggles at all times, or you
will be removed from the lab.

Procedure:
      1. This lab is divided into 6 stations. At each station you will receive the specific procedure for the
         reaction to be performed.
      2. At each station, perform the reaction required, paying special attention to any safety information.
      3. Record the reactants for each reaction on your data table.
      4. Make and record observations for each reaction (there is a column for this provided on your data
         table). Include things like: color changes, precipitate formed, gas formation, temperature changes,
         or other evidence of energy being released.

Conclusion:
1. How can you tell if a chemical reaction has occurred? Mention what were the distinctive changes that you
   observed in each of the reactions in the lab.




2. How can you use the just reactants to determine what type of reaction is going to occur? Name at least one
      hint that you could give a classmate for being able to identify the type of reaction.




Extension:

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) HgO  Hg + O2                                   Type of reaction: _________________________________


Be creative: Come up with an analogy for one of the types of reactions above. Explain it below in full
sentences or draw pictures.
