MSE 430 Fall 2015 Problem Set
Write down a reaction scheme for polymerization of styrene (CH2=CHPh) initiated by thermolysis of azobisisobutyronitrile (AIBN), including both combination and disproportionation as possible modes of termination.
A sample of polystyrene prepared by bulk polymerization at 60°C using radioactive (14C)
AIBN as initiator, was found to have Mn average = 1000 kg mol-1 and a radioactivity of 6 x 103counts s-1 g-1 (measured using a liquid- cintillation counter). Given that the AIBN has a radioactivity of 6 x 109 counts s-1 mol-1, determine the mode of termination which operated in the preparation of the polystyrene sample
This mixture has density of 1.391g/L and occupies a volume four times as that of pure hydrocarbon. Determine the molecular formula of the hydrocarbon.
the system h2g i2g ?? 2 hig is at equilibrium at a fixed temperature with a partial pressure of h2 of atm a partial
graphite and diamond are both made from carbon atoms.a list some of the physical characteristics of each.b give one
The rate constant for a certain reaction is = 6.10×10?3 . If the initial reactant concentration was 0.750 , what will the concentration be after 18.0 minutes
Because the potential of pH electrodes can vary, it is necessary to CALIBRATE a pH electrode before use. For many uses, a two-point calibration procedure is appropriate.
methyl benzoate is an ester which is synthesised from benzoic acid methanol and sulfuric acid. methyl benzoate has a
Calcium nitrate and ammonium fluoride react to form calcium fluoride, dinitrogen monoxide, and water vapor.
When a particular metal is illuminated with photons, one electron is observed for each absorbed photon. What effect would decreasing the wavelength and number of photons, have on the electrons leaving the surface?
Solid aluminum reacts with aq H2 SO4 to form H2 gas and aluminum sulfate. when a sample of Al reacts, 425 mL of H2 gas is produced at 24 degree celsius at a press of 744 mmHg. How man grams of Al reacted?
Carbon dioxide, which is recognized as the major contributor to global warming as a greenhouse gas, is formed when fossil fuels are combusted, as in electrical power plants fueled by coal, oil, or natural gas
An optically activated alkyne A(C10H14)can be catalytically hydrogenated to butylcyclohexane. Treatment of A with C2H5MgBr liberates no gas.
a 1.553 g sample of chymotrypsin is placed into 100.0 ml of water. when this solution was separated from pure water by
