267 moles of NADH are produced by the Citric Acid Cycle (CAC). How many moles of glucose needed to be broken down during glycoly
leva [86]

Answer:

45 moles

Explanation:

From glycolysis, 1 mole of glucose gives 2 moles of pyruvate which undergoes citric acid cycle.

1 mole of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 3 moles of NADH.

Also,

2 moles of pyruvate undergoes citric acid cycle (After conversion to acetyl-CoA) gives 6 moles of NADH.

Thus,

6 moles of NADH are produced from 2 moles of pyruvate or 1 mole of glucose.

1 mole of NADH is produced from 1/6 mole of glucose

267 moles of NADH are produced from \frac {1}{6}\times 267 moles of glucose.

<u>Thus, moles of glucose needed to be broken ≅ 45 moles</u>

How will you separate a solution of benzene and chloroform?
Troyanec [42]

Answer:

\huge\boxed{\sf Distillation}

Explanation:

  • State of benzene at RTP = liquid
  • State of chloroform at RTP = liquid
  • Boiling point of benzene = 80.1 °C
  • Boiling point of chloroform = 61.2 °C

Since, both of the chemicals are liquids, we can separate it by the process of distillation.

<u>Distillation:</u>

  • is the process in which we separate two liquids on the basis of their difference in boiling points.

<u>How it works:</u>

Since chloroform has less boiling point, it will evaporate and collected first and benzene will follow it after sometime.

- Apparatus of distillation is in the attached file.
