Fractional distillation Study guides, Class notes & Summaries

Entc 206- Test 2Polymer - correct answer is a substance composed of molecules with large molecular mass made up of repeating structural units, or monomers, connected by covalent chemical bonds. Synthetic - correct answer describing a substance that has been made artificially thru chemical synthesis; one that does not come from a natural source. Synthetic Polymers - correct answer Fiber, Plastics, Elastomers (or Rubber), protective Coating, Adhesives. What raw material are polymers ma...

What are the 3 byproducts of sugar in fermentation? - CO2, alcohol, heat Boiling Point of Water vs Alcohol - 212/173 What are the 5 things a fermented liquid contains? - water, acid, aldehydes, esters, and congeners What is fractional distillation? - The separation and concentration of two or more liquids with different boiling points What counts as a congener? - Acids, aldehydes, esters, fusel oils, other alcohols Define Heads, Hearts, Tails - 1. Heads - first portion of distillate to com...

Difference between Asphalt and Tar correct answers Asphalt is soluble in petroleum, tar is not. Asphalt has bitumens, tar has low bitumens Two Different Distillation Process to Produce Asphalt correct answers 1. Fractional Distillation: Crude oil is heated, lighter oils vaporize and are drawn off, leaving behind asphalt cement 2. Destructive Distillation: crude oil heated under pressure to higher temperatures than fractional distillation Penetration test correct answers -Test hardness...

temperature is related to KE how? temp is the average kinetic energy thermal energy is related to KE how? thermal energy is the total KE Brainpower enthalpy of fusion is ALWAYS greater than enthalpy of vaporization because? it has to break more bonds (solid --> liquid) the amount of heat depends on (2 factors) 1. the type of substance 2. the amount of the substance during a phase change does temperature change? NO if an archaebacerial species lives in a pool that is 0.01 M HCL wh...

Recapitalization a technique used to purify organic solid compounds with the goal to dissolve and subsequently crystallize a pure substance from the solution. What are the four characteristics of a good solvent? -Target must be soluble in high temp with impurities soluble at room temp or at high temps -Must be chemically inert (non-reactive) -Low boiling point, or highly volatile What are the 5 basic steps to Recrystallization -Choose suitable solvent -Dissolve the impure mixture in the...
