Provide an explanation on why the methylene unit between the two carbonyl groups is more acidic than each of the methyl groups in acetylacetone. In the reaction conditions, what is the base responsible for the deprotonation of acetylacetone
Like sulfuric Acid, a certain diprotic acid, H2A, is a strong acid in its first deprotonation and a weak acid in its second deprotonation. A solution that is 0.020 M H2A (aq) has a pH of 1.66. What is the value of Ka2 for this acid
if H2 of 50.0 mL and C 2 H 4 of 50.0 mL are permitted to react at the pressure of 1.5 atm, produce C 2 H 6 that has a volume of 50.0 mille litres.. compute the amount of (PV )work done?
Using the value of Ksp for Ag2S, Ka1 and Ka2 for H2s, and Kf=1.1x10 to the fifth for AgCl2, calculate the equilibrium constant for the following reaction:
HEPES are synthetic amine compounds that are often used to make buffers for biochemical studies. What is the pH of a 1.0 L buffer solution that is 0.250M HEPES
Fischer projections, isomers, enantiomers and stereocenters, For 2,3-butanediol, there are 3 isomers; 2 are enantiomers, one is not.
The % ionization of a weak acid always declines in a solution that contains the salt of the anion relative to a solution of the acid alone. For example the % dissociation of the acetic acid is less in a solution that contains sodium acetate than i..
A sealed balloon is filled with 2.20 L of helium at 23°C and 1.00 atm. The balloon rises to a point in the atmosphere where the pressure is 210. torr and the temperature is -32°C. What is the change in volume of the balloon as it ascends from 1.00..
