Amixture of lipids is applied to a silica gel column, and the column is then washed with increasingly polar solvents. the mixture consists of phosphatidylserine, phosphatidylethanolamine, phosphatidylcholine, sphingomeylin, palmitate, triacylglycerol, and cholesterol. in what order with the lipids elute from the column? explain your reasoning

Select all that apply. a beta particle: is electromagnetic energy is an electron has zero charge is emitted from the nucleus has a +2 charge has a -1 charge

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

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.
