1. A student carried out a simple distillation on a compound known to boil at 124°C and reported an observed boiling point of 116°-117°C. TLC comparison of the product showed that the compound was pure, and a calibration of the thermometer indicated that it was accurate. What procedural error might the student have made in setting up the distillation apparatus? 2. Which method is better for purifying a mixture of two liquids that boil at nearly the same temperature: simple...

Jenny is 320 N
1. Jenny has made a drawbridge for her treehouse from a hinged wooden plank and a rope as indicated in the figure. The plank weighs 260 N and is 4.0 m long and pivots about the hinge at the left end (which provides an upward force on the plank). When Jenny is x = 2.4 m from the hinged end, what is the tension in the rope supporting the opposite end...

Simple Distillation vs Reflux Simple Distillation Reflux Purpose-Why is it done in Organic Chemistry labs? Purpose-Example of Commercial use of these techniques (include reference link) Equipment-List glassware required, Where is the condenser located relative to the round bottom flask Description-How does it work? Particularly the use of water in the system, evaporation and condensation of liquid etc.
