can you make sure everything makes sense and fill out the rest

Let's break down the data provided in the experiment and check for any missing information.

1. **Mass of beaker:** 83.991 g
2. **Mass of CuCl₂·2H₂O (Copper(II) chloride dihydrate):** 0.5 g
3. **Mass of Al (Aluminum):** 0.25 g
4. **Mass of beaker + Cu(s) (Beaker with solid Copper after reaction):** 64.208 g
5. **Mass of Cu(s) (Solid Copper):** 0.217 g

---

To check if everything makes sense, we can perform some basic calculations and reasoning:

- **Mass of Copper produced:**  
  The mass of the solid copper, 0.217 g, seems to be consistent as it is directly measured.

- **Mass of beaker + Cu(s):**  
  This value, 64.208 g, includes the mass of the beaker (83.991 g) and the solid copper (0.217 g). However, these two should add up to:

  \[
  83.991 \, \text{g} + 0.217 \, \text{g} = 84.208 \, \text{g}
  \]
  The recorded mass of 64.208 g appears to be off by about 20 g, likely a recording or calculation error.

**Filling in remaining **

- To complete the data, you would need to make sure the mass of beaker + Cu(s) is corrected based on the actual measurements. So this value should be:

  \[
  \text{Mass of beaker + Cu(s)} = \text{Mass of beaker} + \text{Mass of Cu(s)} = 83.991 \, \text{g} + 0.217 \, \text{g} = 84.208 \, \text{g}.
  \]

Would you like a more detailed breakdown of the chemical reasoning or stoichiometry behind the experiment? Here's a list of questions to expand further:

1. What was the purpose of using CuCl₂·2H₂O in this experiment?
2. How do you calculate the theoretical yield of copper based on the starting mass of CuCl₂·2H₂O?
3. Is the mass of aluminum significant in this reaction? What role does it play?
4. What are the possible sources of error in measuring the mass of beaker + Cu(s)?
5. How can we verify the purity of the produced copper using the recorded mass data?

**Tip:** Always double-check the scale and measuring tools to ensure accurate recording, as even slight errors can lead to discrepancies in calculations.
