Please help with solving Question 1 (A-C) Thank you!
Unless otherwise specified in the problem, you may assume that all solutions are at 25°C. 1. 50.0 mL of a pH 6.00 carbonic acid buffer is titrated with 0.2857 M NaOH, requiring 17.47 mL to reach the second equivalence point. a. Calculate the molarity of carbonic acid and bicarbonate in the original buffer. Carbonic acid: Bicarbonate: b. Calculate the pH of the solution after a total of 100.0 mL of 0.2857...

4. Only ideal processes can be thermodynamically "reversible." Why can rear proce y can real processes not be? 5. Consider the following reactions. (Note: if this were an exam we would give you an excerpt on tabular data from Appendix 4 (Table A4.3). 2Fe(s) + 3Cla(s) 2FeCl(s) N2H4(8) + H2(g) + 2NH3(g) (a) Would you expect the entropy change for the above reaction to be >0, <0, or no (small)? Justify your answer. (d) Would you expect the entropy change...

(7 pts.) Calculate the heat absorbed when 4.20 g of H2 are produced according to the following equation. CH3OH (g) → CO(g) + 2 H2(g) AH = 90.2 kJ (7 pts.) When one adds 1.475 kJ of heat energy to a sample of gold, the temperature goes from 12.5 °C to 84.6 °C. Calculate the mass of the sample of gold. Gold has a specific heat capacity of 0.129 J/g.°C. (6 pts.) 10. Write the thermochemical equation for the standard...
