Today we did a chemistry scene investigation lab to help us understand limiting reactants. It looks like this:



1.The chemical equation for this lab was:
3CuCl2 + 2Al --> 2AlCl3 + 3Cu
2. We worked with 1.25g of aluminum, 3g of CuCl2, and 175mL of water
3. To complete the lab we had to figure out how many chemicals w
e need to produce 1.8g of copper
4. In the lab some of the CuCl2 was used up, some of the aluminium turned into copper but there was still some aluminum left
5. CuCl2 was the limiting reactant











This is a picture of the CuCl2 and pieces of aluminum from the lab:




Homework:
Answer the 2 questions from the lab:
1.Which supplier made the mistake?
2. How much more of the chemicals will you need?
