Calculate the following for test tubes 3 and 4, and record the results in the table:
the number of moles of zinc used (Use 65.38 grams/mole as the molar mass of zinc.)
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 energy released by the copper(II) sulfate is absorbed by the water.)
the reaction enthalpy, in joules/mole
Answer these for both test tubes
Moles of zinc
Heat absorbed by water (J)
Change in internal energy (J)
Reaction enthalpy (J/mol)

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?
