Albert einstein changed the way we think about gravity by using the results of many new experiments to explain that giant objects like earth bend the space around them. according to einstein, this bending of space makes smaller objects move toward larger objects. which statement best explains whether einstein’s idea is a theory or a law? it is a theory because it is a statement of fact that does not include an explanation. it is a theory because it was developed with many new experiments, and it explained the observations. it is a law because it is a statement of fact that does not include an explanation. it is a law because it was developed with many new experiments, and it explained the observations.

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
