For a particular reaction, Δ H = 120.5 kJ / mol and Δ S = 758.2 J / ( mol⋅K). Calculate Δ G for this reaction at 298 K. Δ G = kJ / mol What can be said about the spontaneity of the reaction at 298 K? The system is at equilibrium. The system is spontaneous in the reverse direction. The system is spontaneous as written.

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

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.
