10. (a) The persistent organic pollutants (POPs) that transport via atmosphere into the Arctic have their unique chemical signature. Explain this statement by comparing their chemical properties with POPs that stay near the source region and appropriate examples. (b) Describe the significance of the global distillation model in understanding the long-distance transport of POPs to the arctic. (c) What are the long-term ecological and human ramifications of POPs contamination in the arctic.

1. Explain how Na2CO3 of primary standard grade can be prepared from primary standard grade NaHCO3? 2. Why is it common practice to boil the solution near the equivalence point in the standardization of acid with Na2CO3? 3. Calculate the molar concentration of a dilute HCl solution if titration of 0.2694 g of primary standard Na2CO3 required 38.77 mL of the acid (products CO2 and H2O).

In addition to preparing financial statements in accordance with GAAP, U.S. companies may be required, in the near future, to prepare financial statements according to International Financial Reporting Standards (IFRS). If the United States adopted IFRS standards, what would be the advantages and disadvantages? Does it make sense for U.S. companies to change to IFRS? How would IFRS impact a comparative analysis of an organization's financial statements?
