In yeast, ethanol is produced from glucose under anaerobic conditions. A cell‑free yeast extract is placed in a solution that co
12345 [234]

Answer:

650 mmol.

Explanation:

The equation for the fermentation of one mole of glucose is:

C₆H₁₂O₆ + 2 NAD⁺ + 2 ADP + 2 P i + 2 NADH → 2 EtOH + 2 ATP + 2 NADH + 2 NAD⁺

Since NAD⁺/NADH is used and regenerated, we can eliminate it from the equation:

C₆H₁₂O₆ + 2 ADP + 2 P i  → 2 EtOH + 2 ATP

With the equation, we calculate the maximum amount of ethanol that could be obtained theoretically:

1000 mmol C₆H₁₂O₆ ------------ 2000 mmol EtOH

325 mmol C₆H₁₂O₆ ------------- x= 650 mmol EtOH

Therefore, the maximum amount of ethanol that could be produced is 650 mmol.

Can someone help with this???

Answer:

2Mg(s) +O₂(g) → 2MgO(s)

Explanation:

Mg(s) +O₂(g) → MgO(s)

When a chemical equation is balanced, the number of atoms of each element is equal on both sides of the arrow. We usually balance O and H last.

In this case, the number of Mg atoms is equal on both sides. Thus, let's move on to balance the O atoms. On the left side, there are 2 O atoms, while there is only 1 O atom on the left side. Thus, write a '2' in front of MgO.

Mg(s) +O₂(g) → 2MgO(s)

Now, the number of Mg atoms is not equal. Write a '2' in front of Mg to balance it.

2Mg(s) +O₂(g) → 2MgO(s)

The equation is now balanced with 2 Mg atoms and 2 O atoms on each side.
