The empirical formula of a compound is determined to be ch, and its molecular mass is found to be 78.06 g/mol. determine the molecular formula of the compound, showing your work.

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a

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.
