The density of acetic acid vapor at the narmal boiling point, 118.5 degrees C, is given as 3.15 g/L (normal boiling point is the boiling point at P =1 atm). a) calculate the fraction of the vapor that is the monomer and the fraction that is the dim..
spontaneous chemical reactions produce products which are more energetically stable than the reactants which form them. A strong acid reacts with a strong base to produce water and the free ions of a salt.
