A definite substance has a heat of vaporization of 52.30 kJ/mol. Explain at what temperature Kelvin will the vapor pressure be 6.00 times higher than it was at 359 K?
What is the pH of a solution that is 0.30 M in aniline, C6H5NH2, and 0.15 M in anilinium chloride, C6H5NH3+Cl-? (Kb = 4.2 × 10-10 for aniline) Aniline ionizes as: C6H5NH2 + H2O C6H5NH3+ + OH-
A gas filled balloon with a volume of 12.5 L at 0.90 atm and 294 K is allowed to rise to the stratosphere where the temperature is 268 K and the pressure is 1.0 millibar. What is the final volume of the balloon ? (1.0 atm = 1.013 bar).
the color change at the endpoint should persist for 30 seconds. Why is this time lapse a good titration technique
