Explain what a high Ka value of an acid represents and what a low Ka value represents. State and explain the difference between the endpoint and the equivalence point in a titration
The absorbance at 595 nm was 0.78 and,according to a standard curve, corresponds to 0.015 mg of proteinon the x axis. What is the protein concentration of the original solution?
Compute the value of the equilibrium constant of the reaction of SO3 as well as water to produce H2SO4 when the concentrations at equilibrium are as follows [SO3] = 0.400M [H2O] = 0.480M [H2SO4] = 0.600M
Given the following equilibrium constant at 25 C, calculate the equilibrium constant for the unknown reaction below.
The osmotic pressure of blood at normal body temp of 37 deg C is 7.65 atm. Sometimes it is necessary to add a saline (NaCl) solution by intravenous injection to a patient in the ER.
1.27 (singlet, 6H); 2.12 (triplet,2H) and 4.26 (triplet, 2H). Determine the structure of the product and draw complete mechanism to show how it is formed.
Caffeine is widely soluble in ethanol. Utilized ethanol instead of dichloromethane to extract the caffeine from tea? Why or why not?
What happens when you cut a bar magnet in half? If it were continually cut in half, would it finally yield two magnetic monopoles? Explain
Describe in detail(ex:individual resins used, etc) the purification of a protein from bovine liver that has the following characteristics
1)Is the form of the plasmid DNA important for the transformation ?how could you tell? 2)What effect does it have on cells that contain pGFP? Does the concentration of arabinose have any effect on these phenotypes?
Copper reacts with any oxygen present as an impurity in the ethylene used to make polyethylene. The copper is regenerated when hot H2 reduces the copper(II) oxide, forming the pure metal and H2O.
