For macroscale distillations, or for microscale distillations usingglassware with elastomeric connectors, compare the plot from yoursimple distillation with that from your fractional distillation. inwhich case do the changes in temperature occur more gradually? which method is more effective in achieving separation? brieflyexplain.

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?

What is special about a dc circuit ?

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel
