Explain why the fluoride ion of the terabutylammonium flouride is more nucleophilic than the fluoride ion of sodium fluoride. Draw reaction-energy diagrams. Define the term, "diastereospecific reaction," and give a representative example.
Examine the bioenergetics of the synthesis of glutamine synthesis from alpha ketogluterate via glutamate synthase or glutamate deyhydrogenase
Gold has a density of 19.3g/ml .suppose you have 100.0 glonkins of gold., what volume in liters will the gold occupy.
At 0.967 atm, the height of mercury in a barometer is 0.735 m. If the mercury were replaced with water, what height of water (in meters) would be supported at this pressure.
Determine the molar concentration of the original hydrofluoric acid solution, and find the pH of the original hydrofluoric acid solution.
What is the concentration of each of the following solutions? a) The molality of a solution prepared by dissolving 25.0g of H2SO4 in 1.30L of water b) The mole fraction of each component of a solution prepared by dissolving 2.25g of nicotine, C4H1..
The iron content of an ore can be determined by a redox titration using K2Cr2O7 as the titrant. A sample of the ore is dissolved in concentrated HCl using Sn2+ to speed its dissolution by reducing Fe3+ to Fe2+.
Calculate the volume the gas will occupy if the pressure is increased to 1.87 while the temperature is held constant.
Calculate the hydrogen ion concentration for an aqueous solution that has a pH of 3.45.
Calculate the pH at the 6 points of titration (fraction titrated = 0, 0.25, 0.50, 0.75, 1.0, 1.25). Hint: Since these concentrations are not the same, first calculate the volume of NaOH required to reach the equivalent point.
Heated and allowed to expand against a constant pressure of 1.20 atm until its volume reaches twenty eight Litres. Now determine Which of the given data is correct?
The gaseous product of a reaction is collected in a 25.0 L contained at 27 degrees Celsius. The pressure in the container is 216 kPa, and the gas has a mass of 96.0g. What is the molar mass of the gas?
8.0 mL of 10.0 ppm fe 2+ solution is diluted to 100.o ml. What is the concentration (in ppm) of the resulting solution?
