A theoretical determination of rosmarinic (RA) and carnosic (CA) acid solubilities in ethanol:water mixtures was also performed using COSMO‐RS and was confronted to experiments. While the best solubilizing solvent (100% ethanol) was also the best extracting solvent for CA, it was not the case...
What is the mole fraction of water in a 3 mol/kg KCl(aq) solution? A mixture is made by combining 1.31 moles of methanol and 1.82 moles of ethanol. What is the mole fraction of each? 4. How many moles of ethanol (CH_3CH_2OH) are in 141 mg?
"Alcohol" is a word that, like a lot of English terms, has a more specific meaning in science than it does in everyday usage. "Ethanol," meanwhile, describes a specific chemical substance; while ethanol is a type of alcohol, it also has multiple applications (one industrial, one food-a...
The taste may also be slightly harsher as there is less water to cover up the flavor of the ethanol. However, because there is more ethanol per volume in high-proof liquors, they are also more potent and can cause intoxication at lower doses than their lower-proof counterparts....
A beaker contains a clear, colorless liquid. It has three chemical substances in it: two of them are liquids and one of them is a solid. How could you determine if it has water, ethanol, and table salt? Remember you're not allowed to taste it. ...
@ Fiorite - You make a good point about the economic impact petroleum subsidies have on ethanol, but I believe for ethanol to truly become a sustainable source of liquid fuel, it must be produced from non-competing crops. Corn is unsustainable because of the amount of fuel per acre, and ...

100% efficient, as the final product is a mix of ethanol, water, and other congeners (chemicals other than ethanol that are formed during fermentation). Relative to other spirits, mezcal has a high level of congeners, which helps explain the elevated complexity and breadth of aromas and ...
prior to the diaphanization process, we performed the dissection of the head, wings, and terminal abdominal segments to macerate them in NaOH 10% and continue with the procedure, while preserving the remaining tissue (thorax, legs, first abdominal segments) in ethanol for posterior DNA ...
Objective: In the present study, we aimed to investigate the presence of fungi that may affect human health in sand and water on Israeli Mediterranean Sea coast beaches. Methods: The study included screening of the sand and water of six urban beaches from north to south on the Israeli Mediter...
