2. Prove by calculating (limiting reactant problem) that iron is the limiting reactant not copper (II) sulfate pentahydrate (Also include a sentence stating your findings.)
3. What was your observation of the filtrant (liquid part that goes through the filter paper) when you filtered out the copper. How does that affect your results.
4. Asuming that iron is the limting reactant, how would the coefficient of the copper and iron (or their ratios) be affected if some of the copper product was left on the stirring rod or table top before drying the product.
5. What is the percent yield of copper?
6. Can you find the percent yield of another compound/element? Justify your answer?
