Fens have acidic water and are fed primarily by rain

FOR QUESTIONS 32 – 37 PLEASE SKIP ONE QUESTION OF YOUR CHOOSING. WRITE “SKIP” FOR YOUR ANSWER. To protect an endangered fish species, managers have implemented new land management practices that have quickly and dramatically reduced nutrient loading to Round Lake. As a result, the lake has shifted from eutrophic conditions to oligotrophic conditions. A. Identify which of these summer temperature profiles is from the lake in eutrophic conditions and which is from the lake in oligotrophic conditions. Letters represent different water layers.  B. What are the names of the water layers (A, B and C) in profile 1? C. Which layer of water is likely to have the greatest concentration of dissolved nutrients at the end of the summer? D. Describe how the dissolved oxygen concentration will vary across the three water layers in profile 1. E. Do you expect to see a greater difference in dissolved oxygen concentration between the top and bottom layers when the lake is eutrophic or oligotrophic? F. This lake was able to recover quickly from eutrophication as external nutrient loading was reduced. Describe the process that could have prevented this quick recovery.

The [ H3O+] of a solution with pH = 5.60 is ________.

Two of the hydrogen atoms in 5-FU are each bonded to one of the two nitrogen atoms in the molecule. Is it possible that the H in this N–H bond can form a hydrogen bond with a water molecule in solution? 

One of the components of cisplatin is ammonia. Draw the Lewis structure of ammonia and identify the central atom hybridization, the molecular shape of the molecule, and classify the molecule as polar or nonpolar. Draw the Lewis structure on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter the following information in the box below.  Central atom hybridization: Molecular shape: Molecular polarity:  polar or nonpolar

The platinum-191 electron capture reaction has a half-life of 3.0 days. If the initial radiation of a 191Pt sample measures 40 mCuries, what will it measure after 12 days?  Include units in your answer. Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter the radiation in the box below.
