While the arenediazonium salts are more stable than their alkane counterparts they do decompose upon heating to temperatures greater thatn 50 degrees celcius. Please illustrate the decomposition of arenediazonium salts using a reaction mechanism and briefly explain why the decomposition produced formed is so reactive.
A student obtains a vinegar solution having an acetic acid concentration of 0.8512 M. What volume of 0.1036 M NaOH will be required to reach the equivalence point when 25.00 mL of the vinegar solution is titrated?
Describe how a distillation works: how can you separate out things with it? which of the functional groups could you easily react via organic reactions to create different compounds

The pH of a sample of rain is found to be 4.0. Calculate the percentage of HSO4- that is ionized in this sample, given that the acid dissociation constant for the second stage of ionization of H2SO4 is 1.2E-2.
If the width of a spectral line of a certain electronic transition is 1.00 cm-1, what is the minimum uncertainty in the lifetime of the transition?
An atom of 125Sn has a mass of 124.907785 amu. Calculate the mass defect (deficit) in amu/atom. Use the masses: mass of 1H atom = 1.007825 amu mass of a neutron = 1.008665 amu 1 amu = 931.5 MeV
