Question

the 3 pages deal with limiting reactant and percentage yield. the mixture starts out as a bright blue and when spinning in the cup smokes ans starts to tirn a black color and the end result is a brown color. then the funnel part was a light blue color.

1. Weigh approximately 7.0 g of CuCl2 and place them in the 100 ml beaker. Record the exact mass in the data table below. Note the appearance of the CuCl2 crystals in the observation section. 2. Add 50 mL of distilled water to the beaker containing the CuCl2 crystals. Stir the solution until all of the CuCl2 crystals have dissolved. Record any observations in the observation section. 3. Weigh out approximately 0.5 g of aluminum foil. Record the exact mass in the data table. 4. Loosely crumple the piece of aluminum foil into a ball. Carefully place it into the CuCl2 solution. Stir the reaction occasionally. Record your observations of the resulting reaction. 5. Set up a ring stand with an iron ring securely attached to it. Place a funnel in the iron ring. 6. Obtain a piece of filter paper and determine its mass. Record the mass in the data table. 7. Fold a piece of filter paper in half and then in half again. Pull one side out and place it in the funnel. 8. Pour the reaction mixture into the funnel to separate the solid from the liquid. Make sure all of the solid is collected in the filter paper. Use a distilled water bottle to rinse the solid from the reaction beaker if necessary. 9. Pour the liquid collected into the waste beaker 10. Allow the filter paper to dry in the hot oven. 11. Obtain the mass of the filter paper and solid. Record the mass in the data
