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.
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 is more polar ethanol or water?
Water is more polar than ethanol. This is because water has stronger hydrogen bonding due to the presence of more hydrogen-bonding sites (two hydrogen atoms and one oxygen atom), making it a better solvent for polar substances. Ethanol is also polar but has weaker hydrogen bonding compared to water.
Which is a better solvent for boiling point elevation ethanol or water?
Ethanol is a better solvent for boiling point elevation compared to water. This is because ethanol has a higher boiling point than water. When a solute is added to ethanol, it will raise the boiling point of the solution more significantly than if the same solute were added to water.
Why is ethanoic acid a stronger acid in liquid ammonia than in aqueous solution?
Ethanoic acid is a stronger acid in liquid ammonia because ammonia is a weaker base compared to water. Therefore, in liquid ammonia, ethanoic acid easily donates a proton to the ammonia molecules, forming the acetate ion. This proton transfer reaction is more favorable than in water due to the difference in the basicity of the solvent.
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.
Which acid is weaker HNO3 or HCO3?
HCO3 (bicarbonate) is weaker than HNO3 (nitric acid). Bicarbonate is a weak acid, while nitric acid is a strong acid. This means that nitric acid completely ionizes in water, while bicarbonate only partially ionizes.
What is more stronger acetic acid or ethanol?
Acetic acid is a stronger acid. Ethanol is an alcohol which is slightly acidic but usually neutral in nature.
Is The conjugate acid of a strong base stronger acid than water?
No, the conjugate acid of most strong bases is water.
Which has the lower freezing point oxygen or ethanol and why?
Oxygen has a lower freezing point than ethanol. This is because the intermolecular forces in oxygen molecules are weaker than in ethanol molecules, allowing oxygen to freeze at a lower temperature.
Which liquid expands more Ethanol or Water?
Ethanol expands more than water when heated because it has a higher coefficient of thermal expansion. This means that ethanol will increase in volume more than water when heated to the same temperature.
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.
Do water acid mercury and alcohol have the same density?
No. They have very different densities. There are several types of alcohol, but for these purposes, we will use ethanol, the alcohol found in drinks. Density of water ≈ 1g/cm3 Density of ethanol = 0.789g/cm3 Density of mercury = 13.5 g/cm3 So water is about 20% denser than alcohol, and mercury is more than 13 times denser than water. Note that the density given from ethanol is for pure ethanol. Most alcoholic beverages are mixtures, with densities between those of water and pure ethanol.
Is vinegar stronger than carbonic acid-?
No, carbonic acid is stronger than vinegar. Carbonic acid is formed when carbon dioxide dissolves in water, whereas vinegar is a weaker acid composed of acetic acid.
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.
Which is the weaker acid HSO4 or H2O?
H2O is a weaker acid compared to HSO4. Water (H2O) has a weaker tendency to donate a proton (H+) compared to bisulfate ion (HSO4-). This is because the dissociation of water into H+ and OH- ions is less favorable than the dissociation of bisulfate ion into H+ and SO4^2-.
Why the reaction of ethanol acid with magnesium is slower than the reaction of hydrochloric acid with magnesium?
The reaction of acetic acid with magnesium is slower than hydrochloric acid with magnesium because acetic acid is a weaker acid compared to hydrochloric acid. This means acetic acid has fewer available hydrogen ions to facilitate the reaction with magnesium. Also, the chloride ion in hydrochloric acid helps to enhance the reaction rate by forming a more stable metal chloride compound compared to the acetate ion in acetic acid.
