An irregularly shaped metal weighs 18.96 g. You measure out a beaker to an initial volume of 50 mL. The metal raises the water level to a final volume of 77 mL. From
this data, what is the density of metal?

fe 55.85 g/mol and h2o 18.02 g/mol.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
