A 13.00 g sample of an ionic compound NaA, where A- is the anion of a weak acid, was dissolved in enough water to make 100.0 mL of solution and was then titrated with 0.100 M HCl. After 550.0 mL of HCl was added, the pH was 5.00. The experimenter found that 1.10 L of 0.100 M HCl was required to reach the stoichiometric point of the titration.
a) What is the molar mass of NaA?
b) Calculate the pH of the solution at the stoichiometric point of the titration.
The reaction will become more spontaneous. B) The spontaneity of the reaction will not change. C) The reaction will become less spontaneous. D) ?G will decrease. E) K will decrease.

Following a terrorist release of Cesium-137 (half-life of 30 years) in downtown, clean up efforts were successful in removing all but 100 curies. How long will it take for the contamination to decay to about 5 curies?
The enthalpy change for the reaction below at 25oC is -1,249 kJ (per mole of C6H14). What is the internal energy change for the reaction at 25oC? 6 CO(g) + 13 H2(g) --> C6H14(l) + 6 H2O(l)
