5. Which of the following is NOT a postulate of the kinetic molecular theory, Circle your answer.
A. Particles in a gas are in constant motion and collide with both one another
and the container.
B. Gas is mostly made up of quickly moving molecules.
C. Pressure is exerted when particles hit the container.
D. Assume particles don't interact with each other (their collisions are elastic
and negligible).

Which statement about the stamps is correct?

If 10.g of agno3 is available, what volume of 0.25 m agno3 can be prepared

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
