Two compounds are standing at the same temperature. Compound "A" is evaporating more slowly than compound "B." According to the Kinetic Molecular Theory, which assumption can be made? Compound A has a greater average kinetic energy. Compound A may have a lower molecular weight. Compound B has a greater average kinetic energy. Compound B may have a lower molecular weight.

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.
