Question- Calculate the pH of a solution prepared by dissolving 0.150 mol of acetic acid and 0.300 mol of sodium acetate in water sufficient to yield 1.00 L of solution. The Ka of acetic acid is 1.76 × 10-5.
I just need a general explanation of it please- Thanks!
When a sample of DNA forms a double helix the measured deltaG is -17 kcal/mol at pH 7.0, 1 M NaCl, and 37 degrees C. If the enthalpy change for this process is -63 kcal/mol. What is the entropy change for this system

Assuming that some of the maleic anhydrisde hydrolyzes prior to the diels alder reaction, what byproduct would you expect to be present after the diels alder reaction is run
A 550 mL volume of hydrogen chloride gas, HCl, is collcted at 27 degrees C and 790 mm Hg. What volume will it occupy at STP?
Problem- Write a balanced chemical reaction, which if you measured its enthalpy would give you the sum of all the C-H, C-C, C-O, & C-H (all the bonds) of C6H12O6 (GLUCOSE).
Problem- We found a theoretical spectrum of HCl for FTIR. Now assume that the isotope Cl 37 was used to generate the same spectrum. How would this heavier mass affect the spacing between the signal peaks?
