Uranium can be isolated from its ores by dissolving it as UO2 (NO3 )2 , then separating it as solid UO2(C2O4)∙3H2O. Addition of 0.4031 g of sodium oxalate, Na2C2O4, to a solution containing 1.481 g of uranyl nitrate, UO2(NO2)2 , yields 1.073 g of solid UO2(C2O4)∙3H2O. Na2C2O4 + UO2(NO3)2 + 3H2O ⟶ UO2(C2O4)∙3H2O + 2NaNO3 Determine the percent yield of this reaction.

1.) Sodium oxalate, Na2C2O4, in solution is oxidized to CO2(g) by MnO−4 which is reduced to Mn2+. A 50.0 −mL volume of a solution of MnO−4 is required to titrate a 0.342 −g sample of sodium oxalate. This solution of MnO−4 is then used to analyze uranium-containing samples. A 4.60 −g sample of a uranium-containing material requires 32.5 mL of the solution for titration. The oxidation of the uranium can be represented by the change UO2+→UO2+2. Calculate the percentage of...

Cu(OH)2 can be obtained from the addition of excess NaOH solution to a solution of Cu(NO3)2 as shown in the figure. If the NaOH is added to 35.0 mL of 0.167 M Cu(NO3)2 and the precipitate isolated by filtration, what is the theoretical yield of Cu(OH)2? Cu(NO3)2 (aq) + 2 NaOH (aq) → Cu(OH)2 (s) + 2 NaNO3(aq) 0.4718 5858 1.10 g 0.570 g 1.14g
