7. A 100 ml sample of 0.100 M NaOH was reacted with 100 ml of 0.100 M HCl in a coffee-cup calorimeter with lid by the following reaction: HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (aq) If the temperature of the water and the calorimeter (heat capacity of calorimeter = 200 J/oK) increases from 25.00 oC to 25.97oC, (1) what is the ΔH of the reaction? Using the definitions at the beginning of the module describe (2) the calorimeter + contents, (3) the type of process.

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.
