Astudent who did the same experiment that you did determined the specific heat for all of the metals. his values were all 0.10 to 0.20 less than the actual specific heat values. select all possible sources of this error listed below.

If 90.0 grams of ethane reacted with excess chlorine,how many grams of dicarbon hexachloride would form

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.

Which of these features are formed when hot groundwater is forced out through cracks in the earth's surface?
