2. For the balanced reaction: 3Mn02 (aq) + 4Al(s) - 3Mn(s) + 2Al203(aq). If I start with 6.0 moles of
Mn02:
A. How many moles of Al are required?
B. How many moles of Mn is it possible to produce?
C. After running the reaction, it's found that only 5.0 moles of Mn were actually produced. What
is my percent yield?

3. For the balanced reaction: Pb (NO3)2 + 2NaCl - 2NaNO3 + PbCl2
24.2g Pb(NO3)2 is reacted with excess NaCl. At the end of the experiment, it is found that 10.3g
NaNO3 is formed.
A. How many grams of NaNO is it possible to form from 24.2g Pb (NO3) 2?
B. What is the percent yield for the reaction?

4. You can dissolve a penny in nitric acid. The balanced reaction is:
Cu(s) + 4HN03 (aq) —> Cu(N03)aq + 2N02 (g) + 2H20(l).
If I have a solution containing 11.34g of HN03.
A. How many grams of Cu(s) is it possible to dissolve? B. l have a copper penny with mass 3.23. Will my penny fully dissolve? Justify your answer.
