You are writing energy balances for a compound for which you cannot find heat capacity or latent heat data. all you know about the material are its molecular formula (c7h12n) and that it is a liquid at room temperature and has a normal boiling point of 200°c. use this information to estimate the enthalpy of the vapor of this substance at 200°c relative to the liquid at 25°c.

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
