Help a) Type several paragraphs describing your “core sample” of Earth’s layers in detail.
i. Explain what a core sample is. Then, tell whether it is currently possible to take a core
sample like the model you’ve created.
ii. Compare and contrast the layers in your model, including the significance of the
colors.
iii. Discuss what it means to create a scale model.
iv. Include a table with the values you determined for each layer.
v. Discuss the relationships of each layer to the others, including depth.

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
