A compound A (C22H27NO) is insoluble in acid and base but reacts with concentrated aqueous HCl and heat to give a clear aqueous solution from which, on cooling, benzoic acid precipitates. When the supernatant solution is made basic, a liquid B separates. Compound B is achiral. Treatment of B with benzoyl chloride in pyridine gives back A. Evolution of gas is not observed when B is treated with an aqueous solution of NaNO2 and HCl. Treatment of B with excess CH3I, then aqueous Ag2O and heat, gives a compound C, C9H19N, plus styrene, C6H5-CH=CH2. Compound C, when treated with excess CH3I, then aqueous Ag2O and heat, gives a single alkene D that is identical to the compound obtained when cyclohexanone is treated with the ylid -:CH2- PPh3. Give the structure of A.
Values for Ksp at O degrees C, 50 degrees C, and 100 degrees C are 1.14X10^-15, 5.47X10^-13, and 4.9X10^-14 respectively. Calculate the pH for a neutral solution at each of these temperatures.

Why do you sweat? Please use all the thermochemical terminologies( endothermic, exothermic, eat transfer, and whatever else is appropriate)
What is the similarity in these diagrams? The sodium ion and the neon atom are isoelectronic (have the same electron configuration).
Why is the boiling point of the parent alcohol (i.e. cyclohexanol) higher than that of the product alkene (clycohexene) in the dehydration experiment
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 ..
Which reagent is used in excess? How great is the molar excess (how many times greater)? I'll add the procedure images in the comments
