Charlie is doing a scientific investigation about the properties of light energy. For his experiment, he points a flashlight at a mirror and then at a basketball. Which of the following best describes what Charlie would observe? (2 points)

Group of answer choices

The light traveled through both objects and refracted which made them appear bigger.

The light was completely absorbed by both objects, and he could see white and blue.

When the flashlight was pointed at the mirror, the light reflected in the same direction. When the flashlight was pointed at the basketball, the light was reflected in different directions.

When the flashlight was pointed at the mirror, the light was absorbed. When the flashlight was pointed at the basketball, the light was refracted in a different direction.

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
