When table salt (NaCl) is added to water, it lowers the freezing point is more salt is added, the freezing point decreases even
more. Why does this occur?
A. When salt is added to water, two jons dissolve, which allows water molecules to more quickly crystallize.
B. When salt is added to water, the dissolved ions interfere with the water molecules aligning to form a solid.
C. When a salt solution is formed, sodium and chloride ions aid water in hydrogen bonding.
D. When a salt solution is formed water molecules become charged and repel each other.

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.
