Acommon laboratory reaction is the neutralization of an acid with a base. when 49.2 ml of 0.500 m hcl at 25.0°c is added to 59.2 ml of 0.500 m naoh at 25.0°c in a coffee cup calorimeter (with a negligible heat capacity), the temperature of the mixture rises to 28.2°c. what is the heat of reaction per mole of nacl (in kj/mol)? assume the mixture has a specific heat capacity of 4.18 j/(g·k) and that the densities of the reactant solutions are both 1.07 g/ml.

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?
