<span>a.       Write the balanced reaction with the correct products.
2Na + CuSO4 = Na2SO4 + Cu

b.       Identify the reaction type (single replacement, double replacement, synthesis, decomposition or combustion).
Single replacement reaction
c. What is the limiting reactant?

10 g Na ( 1 mol / 22.99 g ) = 0.4 mol
60 g CuSO4 ( 1 mol / 159.61 g ) = 0.4 mol

Therefore, the limiting reactant would be CuSO4 since 0.4 mol would be consumed in the reaction.

d.       What is the theoretical yield of copper metal (in grams)?

0.4 mol CuSO4 ( 1 mol Cu / 1 mol CuSO4 ) = 0.4 mol Cu

e.       What is the percent yield if 9.75 grams of copper metal are actually produced?

percent yield = 9.75 g ( 1 mol / 63.55 ) /0.4 mol x 100 = 38.36%</span>
