How much desalinated water did you get? how effective was the solar still in distill the salt water? taste your desalinated water and then the salty water. why does the desalinated water taste different than tap water? discuss the operation of your solar still in terms of thermal radiation, conduction, convection, the change of state of the water, and the conservation of energy. does the size and shape of the outer (evaporating) container affect its efficiency? does the depth (volume) of water in the evaporating container affect its efficiency? any suggestions for improvements?

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.
