A water sample obtained from the neigborhood pond was analyzed
for dissolved oxygen content. A volume of 300 mL, with temperature
21 degrees Celsius, was analyzed using the Wrinkler method shown in
the simulated lab material. It took 15.0 mL of 0.01 mol/L Na2S2O3
solution to reach titration end point.
*Note: Na2S2O3 solution is the source of S2O32- ions for the
titration reaction.

20 liters of water at 20 bar and 100 °C are in a variable volume
container. 56,000 kJ of heat are added to the system at constant
pressure which causes an increase in both temperature and
volume.
Draw a schematic of the process
Write the energy balance for this process and clearly state any
assumptions:
What is the final volume of the container?

of O2 is air, which is about 78.0% N2, 21.0% O2, and 1.0% Ar by
volume. Assuming all the O2 reacts, but no N2 or Ar does, what is
the total volume of gaseous exhaust?
