Post Lab
1 If you percent yield is not 100%, can you explain why it is high or low? Give specific reasons to explain.
2 Could you do anything in this experiment to improve your yield?
3. How do you account for the change in mass of the copper wire? Where does the mass go to or come from?
4 Could you make a profit from this lab? Prove your point with some numbers. Cite your sources for information you used to answer this question.
Explanation / Answer
the percentage yield is not 100% as the moles of Ano3:Cu is not 2:1 thus one of the reactant will remain there will be an equillibrium set here just yield will not be 100% to improve the yield we'll remove some product so that equilibrium moves in forward direction change in mass of Cu is bcoz of the reaction
