What are the advantages and disadvantages of making ethanol from a renewable resource?
Not sure.
What is the difference between fermentation and hydration?
Fermentation is the process of making alcohol (ethanol) by mixing sugar and yeast in a barell: sugar + yeast ----> ethanol + carbon dioxide Hydration is another process of making alcohol (ethanol) by heating water and ethene at a temperature of around 300 degrees celcius under high pressure: ethene + steam -----> ethanol One big difference between fermentation and hydration is that fermentation pproduces the bi-product cabon dioxide whereas hydration doesn't. Another difference coulkd be that the reaction of hydration happens a lot faster than that of fermentation.
Departmentalization by function advantages and disadvantages?
what are advantages & disadvantages of departmentalization by function
What best describes alcoholic fermentation?
The making of wine is an an example of alcoholic fermentation. Yeast consumes the sugars of grapes, changing pyruvate into CO2 and ethanol (the alcohol of wine).
Advantages and disadvantages of matrix?
There are many advantages and disadvantages of having and making a matrix. One advantage is the layout of the information.
Is ethanol carbon neutral or not?
No Ethanol is not carbon neutral as I am about to show you Photosynthesis: 6H2O + 6CO2 => C6H12O6 + 6O2 Fermentation: C6H12O6 => 2C2H5OH + 2CO2 Combustion: 2C2H5OH + 6O2 => 4CO2 + 6H2O by looking at this it would appear that Ethanol is carbon neutral because Photosynthesis uses 6CO2 per mole of glucose, fermentation and Combustion produce 2CO2 and 4CO2 making 6CO2 per mole of glucose but what makes ethanol not carbon neutral is that you have to burn fuel to grow and harvest the crops for fermentation, fermentation requires heat for the reaction to take place, heat comes from energy and energy comes from fossil fuels. ----====---- Only industrial scale ethanol fermentation requires additional heat. Fermentation is a biological process, in which yeast consuming sugars generates alcohol and heat. Small scale ethanol production with hand picked feedstock, is indeed Carbon Neutral.
Can making homemade wine produce co2?
Any ethanol producing fermentation makes CO2, so it's not a matter of can, it will produce CO2.
Advantages of making friends on the internet?
If they have hygiene issues, you won't have to worry. But I believe there are far more disadvantages then advantages.
Audio-visual media advantages and disadvantages?
This media allows you to see and hear the information, making it easier to retain. The disadvantages are that it takes longer to produce.
What is the word equation that creates ethnonol during wine making?
Fermentation is caused by yeast converting sugar into ethanol and carbon dioxide. Incidentally, this occurs in every human body 24/7. It's called endogenous ethanol production.
