A scientist weighed an object at two different locations. The first location was Death Valley at about 86 meters below sea level. The second location was Denali at about 6194 meters above sea level. Which observation would the scientist most likely make about the weight of the object in the two locations? Group of answer choices

The weight of the object would be less on Denali because there would be more mass between the object and the center of Earth.

The weight of the object would be less in Death Valley because the temperature is much higher.

The weight of the object would be greater on Denali due to the centripetal forces of the rotation of Earth.

The weight of the object would be greater in Death Valley because it is closer to the center of Earth.

Which of the following methods uses the decay of atomic particles in an object to find its exact age? a. fossil dating b. geologic dating c. radioactive dating d. relative dating

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
