For each of the following solutions, state whether the solution is saturated, unsaturated or supersaturated in the following conditions: A) at 30o C, 70 g of KNO3 is dissolved in 100 g of water

B) at 20 oC 0 g of KClO3 is dissolved in 100 g water

C) at 100 oC , 30 g of NaNO3 is dissolved in 100 g of water

D) 50 g of NH4Cl at 70o C is dissolved in 100 g water.

Imagine that twenty i.u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?

How do you convert 4 mmol of bromobenzene to ml?

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.
