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...

Thought Questions: 1. A student has accidentally overheated their distillation apparatus so that the cyclohexane/toluene mixture was distilling significantly faster than one drop per second What immediate actions should be taken in order to safely deal with the situation, apart from also sending a lab partner to notify the TA? What must they make certain to avoid doing?
