A chemical change
C6H12O6 (180.16 g/ mol) ---> 2C2H5OH (46.07 g/mol) + 2 CO2 600.4 g glucose @ 92.14 g ethanol / 180.16 g glucose = 307.06 grams of ethanol can be produced 307.06 grams of ethanol @ 0.789g/ml = 389.2 millilitres ========= your answers: 307 grams of ethanol & 0.389 litres of ethanol
The changing of extra glucose into starch is a chemical change.
From one molecule of glucose (sugar) you can obtain two molecules of ethanol. Glucose's chemical composition is C6H12O6 Carbon dioxide (Co2) is lost in the fermentation process so we are left with 2C2H5OH or two ethanol molecules! Hope it helps!
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
co2
Grape juice contains mostly glucose (C6H12O6) and wine also has ethanol (C2H5OH). The ethanol is produced by fermentation of glucose by yeast cells. This is a chemical change.
the chemical equation for glucose to produce ethanol is given below. It is done by The balanced equation for the fermentation of glucose to ethanol is as follows:
C6H12O6 (180.16 g/ mol) ---> 2C2H5OH (46.07 g/mol) + 2 CO2 600.4 g glucose @ 92.14 g ethanol / 180.16 g glucose = 307.06 grams of ethanol can be produced 307.06 grams of ethanol @ 0.789g/ml = 389.2 millilitres ========= your answers: 307 grams of ethanol & 0.389 litres of ethanol
Chemical-changing c02 into glucose
The changing of extra glucose into starch is a chemical change.
1kg of glucose produce 0.5kg of ethanol
From one molecule of glucose (sugar) you can obtain two molecules of ethanol. Glucose's chemical composition is C6H12O6 Carbon dioxide (Co2) is lost in the fermentation process so we are left with 2C2H5OH or two ethanol molecules! Hope it helps!
condensation reaction
Dehydration synthesis. Cellulose is a polymer composed of many glucose molecules attached together.
Glucose is soluble in ethanol.
-1277.36kJ is the heat of combustion of ethanol. It is not the heat of fermentation for the production of ethanol.
In the major pathway of ethanol metabolism the 2 enzymes involved are alcohol dehydrogenase, aldehyde dehydrogenase and thiokinase. ethanol + NAD+ <=> acetaldehyde + NADH + H+ (ethanol dehydrogenase) acetaldehyde + NAD+ <=> acetate + NADH + H+ (aldehyde dehydrogenase) acetate + coA + ATP <=> acetyl coA + AMP + PPi (thiokinase)
