Answer is "2 - C₂H₅OH".
Fermentation is a process which is used to produce energy from sugars (glucose, sucrose and fructose) in the absence of oxygen.
Fermentation with the glucose releases energy by producing carbon dioxide (CO₂) and ethanol (C₂H₅OH) as its byproducts.
The reaction is
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + energy
Answer: avogadros number/constant
Explanation:
I would say there is 10 (2 in the ethyl group, 3 in the three methyl groups and 5 in the pent chain)
Answer:
3.50*10^-11 mol3 dm-9
Explanation:
A silver rod and a SHE are dipped into a saturated aqueous solution of silver oxalate, Ag2C2O4, at 25°C. The measured potential difference between the rod and the SHE is 0.5812 V, the rod being positive. Calculate the solubility product constant for silver oxalate.
Ag2C2O4 --> 2Ag+ + C2O4 2-
So Ksp = [Ag+]^2 * [C2O42-]
In 1 L, 2.06*10^-4 mol of silver oxalate dissolve, giving, the same number of mol of oxalate ions, and twice the number of mol (4.12*10^-4) of silver ions.
So Ksp = (4.12*10^-4)^2 * (2.06*10^-4)
= 3.50*10^-11 mol3 dm-9
