What is the heat of reaction for ethanol fermentation from glucose?
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
What happens when you put frozen ethanol into liquid ethanol?
That question is too vague. I'm assuming you mean a little frozen ethanol into a larger volume of liquid ethanol. This being the case, the ethanol will melt. That's it.
Is ethanol a metal?
No, ethanol is an organic basic liquid, wine and beer contain ethanol, and it is flammable
Formation of ethanol from glucose by yeast a chemical or physical change?
A chemical change
Ethanol CH3CHO - how to write an equation to represent the enthalpy of formation?
CH3CHO+HCl
The latent heat of vaporization of ethanol is 200 calories gram. This means that?
about 200 calories of heat must be added to 1 gram of ethanol to convert it from a liquid to a gas
Why does a few drops of ethanol poured on your arm feel very cold?
Ethanol is an alcohol-based liquid. Alcohols evaporate when warmed - the heat from your arm causes the ethanol to evaporate - taking the heat from your arm as it does, which makes your skin feel cold.
What is the heat of reaction for ethanol fermentation from glucose?
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
Does the formation of solid liquid solutions release or absorb heat?
It could do either.
Does the formation of solid-liquid solutions release or absorb heat?
It could do either.
What is added to change a solid to a liquid?
Heat is added to a solid to make a liquid... this is called melting. some additional liquid (water,ethanol,acid…) also change solid into a liquid.
State of ethanol if the ethanol was 50C?
Liquid.
What is the appearance for ethanol?
Ethanol is a colourless liquid.
Is ethanol a liquid at room temperature?
Ethanol is indeed a liquid at standard temperature and pressure.
Is it OK to heat a flammable liquid such as ethanol using water bath over a Bunsen flame?
yes because the liquid isn't actually touching the flame.
Is cloud formation endothermic or exothermic?
Cloud formation is an exothermic process because heat energy must be released to change a gas to a liquid.
What happens when you put frozen ethanol into liquid ethanol?
That question is too vague. I'm assuming you mean a little frozen ethanol into a larger volume of liquid ethanol. This being the case, the ethanol will melt. That's it.
