Use the reactions given below to determine the ∆H^o rxn in kJ/mol rxn. ½ H2(g) + ½ I2(s) → HI(g) ∆H = 26 kJ/mol rxn
½ H2(g) + ½ I2(g) → HI(g)∆H = −5.0 kJ/mol rxn

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?
