EDTA was used for the aqueous solution titration to determine the amount of calcium ions in the sample. Calculate the fraction of EDTA that exists as Y^4- at pH 10, and from this calculate pCa in 100 mL of solution of 0.100 M Ca^2+ at pH 10 after
The activation energy of a certain reaction is 44.5kJ/mol. At 21, the rate constant is0.0110 s^-1 . At what temperature in degrees Celsius would this reaction go twice as fast?
Carbon from the most recent remains of an extinct Australian marsupial, called Diprotodon, has a specific activity of 0.61 pCi/g. Modern carbon has a specific capacity of 6.89 pCi/g. How long ago did the Diprotodon apparently become extinct? Answe
Evaluate the specific rate constant for the reaction at the temperature for which the data were obtained. The rate-law expression is rate = k[A][B]2
Calculate the pH during the titration of 24.8 mL of 0.736 M HBr(aq) with 0.185 M KOH(aq) after 14.1 mL of the base have been added
