Write equations for the mechanism for saponification using salicylic acid, begin with nucleophillic attack of hydroxide ion on the carbony group of the ester. In lab we did the experiment with benzoic acid and methanol.
At body temperature 37 C, Ka for aspirin equals 3 x10^ - 5.If two aspirin tablets, each having a mass of 325 mg, are dissolved in a full stomach whose volume is 1 L and whose pH is 2, what percent of the aspirin is in the form of neutral molecules
Calculate the percent yield of benzophenone to triphenylmethyl reaction. started with 4.09g of benzophenone and ended up with .682g triphenylmethyl can anyone help me convert these into moles and calculate the yield
A sample of oxygen that occupies 1.00x10^6mL at 575 mmHg is subjected to a pressure of 1.25 atm. What will the final volume of the sample be if the temperature is held constant?
What is the main component of the first eluting peak and what percentage of the total absorbance at 300nm is due to this component?(assuming the light path- length = 1.0 cm)
What is the partial pressure of hydrogen in the collection flask? (Note that the hydrogen is collected over water so there will be gaseous water in the flask along with the hydrogen. At 23°C, the pressure of gaseous water is 21.07 torr. The total ..
