The normal boiling point for a solutionof n-hexane (C6H14, M = 86.18 g/mol) and n-octane (C8H18, M =114.23 g/mol) is T = 93.7 °C. The vapor pressures forthese two compounds at this temperature are pH° = 1496. torrand pO°= 253. torr. Assuming the two compounds form anideal solution, what is the mole fraction of n-hexane in the solution.
Given a buret filled with .11 M acetic acid and a second buret filled with .15 sodium acetate, how many milliliters of each solution should be mixed together to produce 18.0 mL of a solution with a pH of 4.79
Find the pH of the resulting solution when 20.00mL of a 0.1000M triethylamine (CH3CH2)3N (Kb = 5.2x10-4) solution is titrated with 20.05mL of a 0.1000M HCl solution.
The peak was assigned as a Mn-Cl stretching mode of a contaminate manganese chloride species. Why would you expect this to be an erroneous assignment? Suggest a more likely source of this IR absorption.

why a bromine radical is more selective than a chlorine radical during abstraction of a hydrogen on a hydrocarbon?
Acid rain was at one time an important point of contention between the United States and Canada. Much of this acid was the result of the emission of sulfur oxides by coal-fired electricity-generating plants in southern Indiana and Ohio
