Why does fractional distillation result in better separation of two liquids with similar boiling points compared to simple distillation? 1. What would be the effect on the observed melting point if sample were: a) too small- b) too large - c)...
When should a fractional distillation be used instead of a simple distillation? Where in the infrared spectrum would you expect the given compound to absorb? How does the infrared spectrometry machine work and what is it used for? Why doesn't the indicator affect the titration results in the ...
Although all prior steps leading up to the fractional division are valid, the local refinement model is forced to either attempt the difficult operation again or choose the wrong operation entirely. In contrast, the global refinement model may attempt to solve the problem with an entirely new ...
