You are doing field work on a small, uninhabited island. You are supplementing your food supply with fish that live in some of the ponds on the island. You catch a brightly colored fish with red and black stripes. You filet it, pan fry it, and spit out the first bite because it tasted like it had been soaked in urine. Back at camp, your guide from a nearby island is pan frying fish with red and black stripes he caught in an adjacent pond. When you tell him not to eat those, he smiles and says these are the best tasting fish in the whole island chain. You look closer and see the pattern of the red and black stripes is just a little different from the fish you caught. What principle of ecology have you experienced firsthand?

M is the made-up metal element mysterium. A lab technician adds 1.60 g of solid sodium fluoride to 1.00 L of a 0.00030 M solution of mysterium(III) nitrate, M(NO3)3. (Assume no change in volume.) Ksp = 9.4×10-9 for the slightly soluble salt mysterium(II) fluoride, MF3 . Calculate the ion product Qsp under these conditions and report the value here. [B] You must show work supporting your answer for full credit. You’ll be asked to explain whether a precipitate of MF2 will form or not in the next question, so make sure you have the necessary data in your work before going on.
