The following image is a prediction of how an earthquake would spread from the epicenter (marked by a star). Red indicates the worst areas, and green indicates the places where there is the least shaking. Water is colored blue. Consider a seismic wave—an earthquake—that starts in the middle of the red area and travels outward along the surface of the earth. Point A is the same distance from the epicenter as point B. Using what you know about the movement of waves, how would you expect the seismic waves to be different at point A and point B?

A.
The ground would shake up and down at point A but back and forth at point B.

B.
The waves would be larger at point A than at point B.

C.
The waves would be exactly the same at points A and B.

D.
The waves would arrive at point B before they arrived at point A.

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
