Rxn Use the ΔΗ° and ΔΗ°, information provided to calculate AH°F for SO3(g):
AH f (kJ/mol) 2 SO2(g) + O2(g) → 2 SO3(9) AH°rxn = -198 kJ
SO2(g) -297

Stage in which a typical star has completely stopped fusion

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.
