A chemist is studying the boiling points of 12 related compounds. She reports that the average boiling point is 65.5 degrees Celsius. What can be concluded from this information? A. If any compounds boils at a temperature greater than 65.5 degrees Celsius, then at least one compound must boil at a temperature less than 65.5 degrees Celsius.
B. All 12 compounds boil at a temperature of 65.5 degrees Celsius.
C. None of the 12 compounds boil at a temperature of 65.5 degrees Celsius.
D. A boiling point of 65.5 degrees Celsius is the most common boiling point among the 12 compounds.

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.
