Calculations (SHOW ALL WORK FOR FULL CREDIT)
1. Mass of iron used in the reaction
2. Mass of copper II chloride used
3. Mass of copper metal produced
4. Moles of iron used
5. Moles of copper produced
6. Atoms of iron used
7. Atoms of copper produced
8. Calculate the ratio of moles of copper produced to moles of iron used. Simplify to smallest numbers.
9. Was there any evidence that some of the copper II chloride solution was left in the beaker? Explain your answer.
10. What is the name of the type of reaction you just observed?
11. Write the balanced equation for the reaction. (yes, you must predict the products formed, one of them is an iron II
compound)
12. Compare the mole ratio from your calculations (Q #4 & 5) to the mole ratio from the balanced equation. Explain your
results briefly.
