You perform a fractional distillation of a 100 mL mixture of ethyl acetate (BP 77), toulene (BP 111), and dimethylformamide (BP 153). You monitor the temperature of the vapor, and notice rapid increase in the vapor temperature after 34 mL of distillate, and then again after 89 mL of Distilate. How many mL of Toulene were in the mixture? A. 11 B. 100 C. 55 D.89 E. 34

After performing a fractional distillation and determining my two substances in an unknown mixture were methane and water with 4 mL of distillate collected at 64.5 C, 1 mL collected at 80 C and 10 mL collected at 100 C (total starting volume was 25 mL, did not distill to dryness) I am asked to plot distillation volume vs. still head temperature and then draw a line on the distillation plot that explains how to find percent composition of each...

rewrite text in past tense Procedure-Simple Distillation 1. Take 60 ml of a 50:50 mixture of cyclohexane and toluene and place in a round bottom flask. Make sure you add a few boiling chips. 2. Assemble the distillation apparatus (See Figure 2.) and start the water flowing through the condenser. Place a graduated cylinder under the bent adapter so that you can measure the volume of distillate you collect. 3. Begin heating the sample with a heating mantle until it...

Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
