    1. Purpose
    • 1. Lavel test tubes throgh
    • 2. Follow the instructions for the reaction
    • 3. Write formulas for reactans in your table
    • 4. Predict the products by writing the full chemical equation for the reaction.
    • 5. Balance the equation. Classify the reaction.
    • 6.Record observations about all details of the reaction.
    • 7. Keep the test tubes containing reactions in a rack.
    • 8.Record any additional observations from changes that ocurred over the lab period.
    • 9. When finished, clean the equipment you used and put it away.
  • 4. EXPERIMENT 6
    • Station 6:

  • 5.  
  • 6. EXPERIMENT 1
    • Station 1:
    • Test tube 1: In one test tube, mix a few pieces of solid zinc metal with two dopper-fulls of copper (II) nitrate solution. Look closely at the Zn in the tube, and then note the color of the solution .
