1.45-g sample of oxalic acid, H2C2O4, is dissolved in distilled water to make 50.00 mL of aqueous solution. This solution is called “Solution A”. The 5.00 mL of Solution A is added to 20.00 mL of distilled water to make “Solution B”.H2C2O4(aq) reacts with MnO4–(aq) to produce CO2(g) and Mn2+(aq).When 19.41 mL of H2C2O4(aq) (Solution B) is mixed with 21.59 mL of 0.0400 M MnO4–(aq), the mass of CO2(g) obtained is 0.0990 g.(a) In this chemical reaction, which substance is the oxidizing agent? Why?(b) Calculate the percentage yield of CO2(g).(c) Determine the molarity of the excess reactant at the end of the chemical reaction.
