Please help Question 1. Manatees cannot survive in cold water. Therefore, they migrate to the warm Florida coast for the winter. Give an example of another animal that migrates when the seasons change. Describe why they migrate and where they start and end their journey.

Question 2. Why are the manatees concentrated in such high numbers at the Three Sisters Springs?

Question 3. Where might you expect to find organisms behaving similarly to the manatees during a cold front?

Question 4. How do Florida plants and animals respond to seasonal changes?

Question 5. How do the seasonal changes of animals and plants in a northern region (such as New York) compare to those of Florida?

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)

Avariable that is not being directly tested during an experiment should be

16. in a reaction that has reached equilibrium, a. the forward and reverse reactions are occurring at the same rate. b. the reactants and products are in equal concentrations. c. the forward reaction has gone further than the reverse reaction. d. there are equal numbers of atoms on both sides of the equation. e. a, b, and d are correct.
