You are given the following boiling point data, Which one of the liquids would you expect to have the highest vapor pressure at room temperature! a. ethanol, CH3CH2OH 78.5°C b. water, H20 100°C Oc. diethyl ether, CH3CH2 O CH2CH3 34.5°C Od. ethylene glycol, HO CH2 CH2 OH 198°C Oe methanol, CH3OH 64.96°C
What would you expect the observed boiling point to be at 10 torrs of a liquid which has a boiling point of 300 °C at 760 torrs? (Use Figure) Would it be possible to establish the composition of an unknown binary mixture of two substances from mixture melting-point data? Explain. After recording the R values using as a solvent system ethyl acetate and hexane (1:4), determine what solvent system is needed to obtain values between 0.3-0.4 for each of the...

How would a gradient elution(60 C-140 C) impact the
chromatogram?
Mobile Phase - Air (Flow Rate = 20 mL/min), Stationary Phase - poly(dimethylsiloxane), Oven Temperature - 75 °C. Ethane-1,2 diol (ethylene glycol), butanone, 1-butanol, 2-butanol In gas chromatography (GC) which component elute first depends on the boiling point. In GC the mixture is first converted to its gaseous states and then passes through the column. The component which has lowest boiling...
