What is the wavelength in nanometers of a photon with a frequency of 6.10 ? 10^14 sec-1? (The speed of light in a vacuum is 2.998 ? 108 m/s. Planck's constant is 6.626 ? 10^-34 J·s.)
Calculate the expected pH values of the buffer systems from the experiments (a, b, c, d) using the Henderson-Hasselbalch equation (pH= pKa + log [A-] ). Use for pKa values: carbonic acid= 6.37 and acetic acid= 4.75.
A certain bike tire deflates (via effusion) through a hole in 60.00 minutes when filled with pure Nitrogen gas. If the same bike tire, inflated to the same pressure with an unknown gas under all the same conditions, deflates in 71.71 minutes, what..
