The condensation of Acetone (AH) in aqueous solution is catalyzed by bases, B, which react reversily with acetone to form carbanion, A- plus the rotonated base, BH+. The carbanion then reacts with a molecule of acetone to give the product. Assuming the steady state approximation is valid, determine the concentration of the carbanion and derive a rate equation for the formation of product (remember this rate equation should not include any intermediates)
HA + B ---> BH+ + A- A- + HA ---> Products
the specific heat of an unknown metal is found to be 0.233 j kg. The law of dulong and petit predicts a molar heat capacity of J/K mol. Use this law to estimate the molar mass of the element.
Suppose a solution contains 0.25 M Pb2 and 0.49 M Al3 . Calculate the pH range that would allow Al(OH)3 to precipitate but not Pb(OH)2
(a) Can you suggest a reason that accounts for this unusual behavior? (b) Suggest an experiment with labeled compounds that would confirm this mode of attack.
