Which statement accurately describes what happens when water turns to ice in terms of energy? a. the water absorbs energy which causes chemical bonds to form, changing water into ice. b. the water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a solid. c. the water releases energy which causes chemical bonds to form, changing water into ice. d. the water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to solid.

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.
