When an earthquake occurs, two different types of waves are generated. These waves are called P waves and S waves. Examine the diagram, which shows how the waves travel through Earth. Which statement provides the best evidence of Earth’s structure, based on the information in the diagram? A. The bending of S-waves shows that Earth has both an outer and an inner core.

B. Earthquakes provide no information because they cannot be detected all over Earth.

C. S-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.

D. P-waves do not travel through liquids, so the evidence shows that Earth has an outer core layer made of liquid.

From the choices provided below, list the reagent(s) in order that will react with cyclopentanone to form the compound shown below.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
