5.(06.01 MC) Part 1. A glass bottle, which is half-filled with water, has a balloon attached to its opening. The bottle is placed in a hot water bath for some time. Explain the change to the size of the balloon
based on the kinetic molecular theory.
Part 2. What would most likely happen to the balloon if the bottle was then placed into a jar of cold water with ice cubes? Explain your answer based on the kinetic molecular theory.
In both cases, assume the balloon is attached tightly enough so that air does not escape the system. (8 points)

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
