Calculate the following for test tube 1 and for test tube 2, and record the results in the table:
the number of moles of copper(II) sulfate used (Use 159.60 grams/mole as the molar mass of copper(II) sulfate.)
the heat absorbed by the water, in joules (Use Q = mCΔT, where 10.0 milliliters of water has a mass of 10.0 grams. Use 4.186 joules/gram degree Celsius as water’s specific heat capacity.)
the change in internal energy of the copper(II) sulfate (Assume that the energy released by the copper(II) sulfate is absorbed by the water.)
the reaction enthalpy, in joules/mole

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?
