When a paper chromatography was completed on a three-component mixture, only two spots appeared on the paper. What conditions or parameters would need to change to separate the overlapping components? How does polarity affect chromatography?
Chromatography As stated earlier, chromatography is used in laboratories to separate or quantify the mixtures of organic compounds. For this purpose, it utilises the polarity difference in molecules, and the compounds get divided based on their affinity towards the stationary phase. There is also one...
How does molecular weight (size of a molecule) influence its rate of diffusion? What are some factors that can alter the speed of diffusion? How is facilitated diffusion different from regular diffusion? How did the surface area affect the diffusion of the cube? Does polarity affect the rate ...
摘要原文 Plants often make the same organ in different development contexts. Roots are a quintessential example, with embryonic, primary, lateral, adventitious, and regenerative roots common to many plants. The cellular origins and early morphologies of different roots can vary greatly, but the adult...
scientists noticed entanglements in synthetic polymers51, and found polymer composition, polarity, and tacticity can lead to alteration in the frequency and strength of entanglements. And entanglements due to loop threading in proteins have been found to be more common in the case of larger protein...
In contrast, carbonyls such as carcinogenic formaldehyde and acetaldehyde, acting as ozone precursors, were effectively scrubbed due to their polarity and water solubility. The ozone formation potential (OFP) of all fuels was examined. Significant EF differences between fuels and engine loads were ...
from high to low polarity (Vanden Berghe and Vlietinck, 1991). This permits better discrimination between fractions that exhibit aspecific activity or cytotoxicity and fractions that show selective antimicrobial activity. This ‘primary’ fractionation scheme may also contain dereplication steps to avoid...

How does polarity affect chromatography? Explain how body water and volume of distribution affect the distribution of a chemical. What are the effects of acid rain on the ecosystem (soil, water, plants)? What is the disadvantage of crystallization over evaporation?
How does polarity affect chromatography? Explain what a flame test has to do with spectroscopy. How does the saturation of a solution affect crystal formation? What is the effect of NH_3 (aq.) and HCl (aq) on the CuSO_4 or NiCl_2 solution? What are the two methods used for...
