Lf the attractive forces among the solid are less than the attractive forces between the solid and a liquid, the solid will?

a) dissolve as particles are pulled away from crystal lattice by the molecules

b) probably form a new precipitate as its crystal is broken and reformed

c) be unaffected because attractive forces within the crystal lattice are too strong for the dissolution to occur

d) begin the process of melting to form a liquid

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.
