Ok, I'm having great difficulty with this lab. I'll write down the questions and the facts that I have, any help would be greatly appreciated.
Question: What mass of copper is formed when excess aluminum is reacted with a given mass of copper(II) chloride dihydrate.
Prediction: Calculate the theoretical yield for this experiment
A known mass of a copper salt is dissolved in water and is reacted with an excess of aluminum. The mass of copper is formed in the reaction is determined. The balanced equation is:
3 CuCl2.2H2o (aq) + 2 Al (s) ---> 3 Cu (s) + 2 AlCl3(aq) + 6 H2O(l)
We have 2.00 g of copper (II) chloride dihydrate.
Analysis: Identify the limiting and excess reagent in this reaction. What visible evidence is there to confirm your identification?
Determine the actual yield of copper
Determine the percentage yield of copper
If your percentage yield is less than 100% suggest scientific techniques or equipment the percentage yield that may account for the loss of product.
PLEASE HELP!!!!!!!!!!!!
