While the way in which nitrogen moves throughout different reservoirs on Earth makes up a cycle, it is not a process that exists within a bubble. The different components of the nitrogen cycle interact either directly or indirectly with other cycles, such as the oxygen and carbon cycles. What are some ways that the nitrogen cycle overlaps with or influences the oxygen and carbon cycles? Are any of these interactions between the cycles positive? Are any negative? What about when the nitrogen cycle is thrown off balance by the Haber-Bosch process and others like it? How can that influence the oxygen and carbon cycles? Are there other cycles involved that have not been mentioned in this question? Finally, what does this discussion suggest about the nature of the Earth as one large system?

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.
