Check all the TRUE statements on fractional distillation Select one or more: A boiling chip is required to help avoid bumping during distillation. The West condensor is packed loosely with steel wool. The rate of distillation should not exceed 15-20 drops per minute. Fractional distillation has more theoretical plates than simple distillation. The distillate should be disposed of in the non-halogenated waste container The water runs in the condenser from top to bottom In this experiment, the distillation apparatus is heated by a Bunsen buner

Check all the TRUE statements on fractional distillation. Select one or more: A boiling chip is required to help avoid bumping during distillation. The West condensor is packed loosely with steel wool. The rate of distillation should not exceed 15-20 drops per minute Fractional distillation has more theoretical plates than simple distillation. The distillate should be disposed of in the non-halogenated waste container. The water runs in the condenser from top to bottom. In this experiment, the distillation apparatus is heated by a Bunsen burner Indicate the true statement(s) below on gas chromatography (GC). Select one or more: Gas Chromatography uses a carrier gas that helps push the material through the chromatography column. O Only gases can be injected into a gas chromatograph. The oven of a GC is used to char the material being analyzed to obtain elemental analyses. The two phases (solid and gas) are employed in gas chromatography. The detector is used to determine the presence of the material as it exits the column. Different materials will generally travel through the column at different rates of speed. Thus, they are separated over time. The stationary phase, helium, is used to blanket the material from burning completely What is the correct position of the thermometer bulb in the simple distillation apparatus?

What is the correct position of the thermometer bulb in the simple distillation apparatus? Select one: 1 inch above the bottom of the flask. 1/2 inch above the liquid level. 1/2 inch below the side-arm of the distillation head. At the bottom of the graduated cylinder. 1 inch below the liquid level. The thermometers use alcohol now, so placement is not an issue.
