How is an occluded front different from a cold front?
warm air is pushed up during an occluded front, while cold air moves quickly during a cold front.
occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler.
warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front.
occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation

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.
