Ethanol is soluble in water due to its ability to form hydrogen bonds with water molecules. Ethanol contains a hydroxyl (-OH) group that can participate in hydrogen bonding with water molecules, allowing it to dissolve in water. In contrast, propane is a nonpolar molecule with only weak van der Waals forces between its molecules, which are not strong enough to overcome the strong hydrogen bonding in water, making it insoluble in water.
What else can I help you with?
What is the word equation for burning ethanol?
Ethanol+oxygen-carbon dioxide+water
Why does ethanol burn differently than ethanol and water mixed?
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
Can steam distillation of ethanol be done using a mixture of ethanol and water?
Yes, steam distillation of ethanol can be done using a mixture of ethanol and water. The mixture will allow for separation of the ethanol from the water by taking advantage of the difference in boiling points between the two compounds.
Why is water a better conductor than ethanol?
Water is a better conductor than ethanol because it contains ions that can move freely and carry electrical charges, while ethanol does not dissociate into ions as readily. This means that water can facilitate the flow of electricity more easily than ethanol.
What effect does adding water have on the boiling point of ethanol?
Adding water to ethanol lowers its boiling point. This is because water forms an azeotrope with ethanol, which alters the vapor pressure of the mixture, resulting in a lower boiling point compared to pure ethanol.
Which material would require the least amount of energy to change 1kg from a solid to a liquid ethanol aluminum propane or water?
Water would require the least amount of energy to change 1kg from a solid to a liquid because it has a lower melting point compared to the other materials listed (ethanol, aluminum, propane).
Which is more soluble in water propane or ethanol?
Ethanol---it has stronger intermolecular forces due to its ability to hydgrogen bond (because it has an -OH group) that propane. Both of them have similar dispersion forces because they have around the same number of electrons, so the presence of hydrogen bonding in ethanol will give ethanol the greater intermolecular forces and hence the higher surface tension.
Why ethanol have higher boiling point than propane?
Ethanol has a higher boiling point than propane because it has stronger intermolecular forces due to hydrogen bonding between its molecules. Propane, on the other hand, is a small nonpolar molecule with weaker London dispersion forces between its molecules. This leads to lower energy required to break the intermolecular forces in propane compared to ethanol, resulting in a lower boiling point.
What are some highly flamable substances?
Gasoline, paper, wood, ethanol, propane, etc.
What has the author Marco Franzoso written?
Marco Franzoso has written: 'Edisol-M. Water Solubile' 'Westwood Dee-Jay'
Does ethanol contain water?
Yes, ethanol can contain water as it is a common impurity in ethanol. Ethanol is a type of alcohol that can be mixed with water.
What are three alternatives to gasoline for automobiles?
gas, diesel and electricity Ethanol, natural gas, propane,
What types of fuel are used in automotive engines?
Gasoline, diesel, ethanol, propane, natural gas,
Which two are miscible with one another oil water and ethanol?
Water and ethanol. Oil is immiscible with either of those.
What can you use instead of petrol in your cars in the future?
diesel Ethanol Natural Gas Propane Battery power
Which fluid will float 5 kg of ethanol or 1kg of water?
1 kg of water will float in ethanol because ethanol is less dense than water.
How to obtain pure water and ethanol from a mixture of sea water and ethanol?
You would use distillation, in which the ethanol and water will boil at different temperatures.
