Use the Henderson- Hasselbalch equation to calculate the pH of
each solution.
a. a solution that is 0. 145 M in propanoic acid and 0. 115 M in
potassium propanoate
b. a solution that contains 0.785% C5H5N by mass and
0.985% C5H5NHCI by mass
c. a solution that contains 15.0 g of HF and 25.0 g of NaF in
125 mL of solution

what is the question?

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
