Waarom lost hexaan niet op in water?
Hexaan (C6H14) is een bestanddeel van benzine, dus lost niet op in water. Je kan dus concluderen dat hexaan hydrofoob is! Ethanol (C2H5OH) kan met een waterstofmolecuul een waterstofbrug vormen, dus is oplosbaar in water (hydrofiel).
Wat doet een Micel?
Een micel is een microscopisch kleine structuur van een aantal moleculen van een oppervlakte-actieve stof in water. In het centrale deel (de hydrofobe staarten) van een dergelijke micel kunnen ook andere hydrofobe stoffen gevangen worden, wat de vetoplossende werking van zeep verklaart.
What happens when C2H5OH is mixed with water?
When C2H5OH is mixed with H2O (water) there isn’t a chemical reaction (no new substances are formed). Instead, because both C2H5OH and H2O are polar molecules, the Ethanol and water are able to mix together. To show that the Ethanol has mixed with water water we can write (aq) after it. The (aq) shows that it is aqueous.
How do you balance C2H5OH + O2 = CO2 + H2O?
In this video we’ll balance the equation C2H5OH + O2 = CO2 + H2O (ethanol and oxygen gas) and provide the correct coefficients for each compound. In order to balance C2H5OH + O2 = CO2 + H2O you’ll need to watch out for two things. First, be sure to count all of C, H, and O atoms on each side of the chemical equation.
What is the chemical name of the compound C2H5OH?
C2H5OH or Ethanol can simply be called or termed alcohol and it is an organic chemical compound. The compound can also be represented as CH3-CH2-OH. Ethanol is a colorless liquid with a distinct odor and a pungent taste. It has flammable properties; when burnt, the compound gives a blue color flame.
What is the degree of dissociation in C2H5OH with no dissociation?
For C2H5OH (no dissociation) i=1 since no dissociation. Hope it helps. The degree of dissociation of an acid HA is given as 1.82%. At a constant temperature and 1 ATM pressure, the degree of dissociation is 0.2. Additionally, how does ethanol dissociate in water?
