Explain what is the sedimentation velocity of a 0.0008m floc with a particle density of 1200 kg/m3 if absolute dynamic viscosity is 0.000547? Utilize stoke's law.
The rest mass of a proton is 1.0072764669 u and that of a neutron is 1.0086649156 u. The 75As nucleus weighs 74.92160 u. Calculate the total binding energy of the nucleus.
A method of analysis yields masses of gold that are low by 0.4 mg. Calculate the percent relative error caused by this result if the mass of gold in the sample is
Propose a reasonable reaction mechanism for the sodium hypochlorite oxidation of 3-heptanol. Give the IUPAC name of the expected product
Suppose the calorimeter for this experiment had been made of a heat-conducting material (such as metal) rather than plastic foam, so that the portion of heat energy lost to the calorimeter itself was larger and could not be ignored
Explain how the presence of the intramolecular hydrogen bonding in the single-deprotonated maleic acid could lead to differences in the acid-dissociation constant when compared to fumaric acid.
Why is the angular momentum of some nuclei and molecules observable. How is it observed? What are some typical results.
The isoelectric point (pI) of a peptide is the pH at which the peptide does not migrate in an electric field. Since the peptide is zwitterionic, there are the same number of positive charges as negative charges on the peptide population.
what would happen if the bottle was labeled salicylic acid from benzene actually contained acetylsalicylic acid
