Question

After the chemistry lecture on single replacement redox reactions, your classmate tells you he has come up with a plan to produce gold and get rich. His plan involves ordering 325.00 mL of a solution of aqueous Au(NO3)3 {gold(III) nitrate} at 0.0255 M and 13.457 g of Sn (tin) from a chemical company.

g) Calculate the maximum mass of gold that can be produced from the supplies he will order. Show work clearly.

h) The supplies arrive and your friend prepares to run the experiment. However, in the process of getting the lab set up, he gets interrupted and leaves the cap off the bottle of the Au(NO3)3 solution by accident. He is unable to return to the lab for another 2 weeks. In that time, 40.00 mL of water evaporated and the aqueous Au(NO3)3 solution is now 285.00 mL. If he runs the reaction now, would your answer to part (g) change? If so, by how much? If not, why not? Show calculations to support your answer. Give your answer in coherent complete sentences.

i) If the current price of gold is $1337.59 per ounce and the cost of Au(NO3)3 is $280.00 per 20.00 mL at 0.0255 M, is this reaction economical? In other words, will he make a net profit? (1 ounce = 28.35 g) Show calculations to support your answer. Give your answer in complete sentences.

j) Do you think that this experiment to produce gold in the laboratory will draw worldwide attention? Explain your answer using complete sentences.
