Assume that a container of liquid purified water at p-1 bar can be superheated to reach t 376 k without boiling. a nucleation event then takes place and the water quickly reaches equilibrium. a. calculate the percentage volume increase upon the nucleation (i. e. how does the volume of the remaining liquid and produced vapor compare to the volume of the liquid prior to use heat capacity at constant pressure value 4.215 j/(gk). the enthalpy change on vaporization at t-373 k is hy- hl 2257.4 j/g. the specific volumes of vapor and liquid are v 1.6939 m3/kg and vl-0.00104 m3/kg.

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
