1 answer:
Answer:
FADH2 is a reducing agent.
FAD is an oxidizing agent.
Explanation:
The full form of FAD is flavin adenine dinucleotide. It is mainly a redox-active coenzyme which is associated with the different proteins and is involved with the enzymatic reactions in the metabolism.
FAD is obtained by donating or accepting electrons.
In the citric acid cycle,
succinate + FAD → fumarate +
Thus we see that FAD is an oxidizing agent while is a reducing agent.

Taking into account the definition of percentage composition, the percent composition of carbon in this sample is 62.17%.
<h3>Percentage composition</h3>The Percentage Composition is a measure of the amount of mass that an element occupies in a compound and indicates the percentage by mass of each element that is part of a compound.
Then, the percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.
In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:
In this case, you know:
- mass of solute= 46.63 g
- mass of solution= 75 g
Replacing:
Solving:
<u><em>percentage by mass= 62.17 %</em></u>
Finally, the percent composition of carbon in this sample is 62.17%.
