a) You have a protein that undergoes conformational change from folded state(F) to unfolded state(U) depending on pH. For each state draw a graph for how scattering intensity might change with time.
b) For the graphs in part a, construct corresponding graphs that depict how autocorrellation changes with ?.
c) Name a molecular paraameter that could be directly extracted from the fit of the autocorrelation function in part b.
If the barometric pressure is 784 torr and the experiment is carried out at 25 oC, what is the pressure of the gas collected?
Consider the following equibrium: CO(g) + 3H2(g) = CH4(g) + H2(g) Initially, 0.200 mol CO and 0.600 mol H2 are placed in a 2.00 L container.
A nonelectrolyte solution adsorbs on an electrically neutral solid through a liquid. Two surfaces of this type are brought close to one another in the liquid such that they interact.
explain why it is dangerous to mix solutions in a test tube by placing a finger
The temperature of the water and that of the gas are identical at 26oC. how many moles of helium have been evolved.
a solid block of exactly 100.0 cm3 has a mass of 153.6g. Determine its density. will the block sink or float in water
A single crystal of a metal is oriented for a tensile test such that its slip plane normal makes an angle of 65.5° with the tensile axis. Three possible slip directions make angles of 30°, 48°, and 78° with the same tensile axis.
Is there an analytical technique we could employ to verify that the camphor is also racemic? What type of instrument would you use? What kind of results would you expect from a racemic product?
You are asked to prepare an aqueous solution of ethylene glycol (HOCH2CH2OH) with a mole fraction of 0.142.
Zinc has two isotopes. Zn-64 has an atomic mass of 63.9292amu and Zn-72 has an atomic mass of 71.9278amu. Its average atomic mass is 65.38amu. Calculate the abundance, in percent, of Zn-64.
A fixed quantity of gas at 24 C exhibits a pressure of 745 torr and occupies a volume of 4.40 L. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant.
A solution was prepared by mixing 43.00 mL of 0.190 M HNO3 and 108.00 mL of 0.150 M HNO3. Calculate the molarity of the final solution of nitric acid.
