Answer:
The reaction between 3-nitrophthalic acid and hydrazine is highly vigorous. Therefore, the answer is <em>option C</em>.
Explanation:
Triethylene glycol is a high-boiling solvent which necessarily used to contain the synthesis of luminol, which is obtained from the reaction between 3-nitrophthalic acid and aqueous hydrazine. However, this reaction is carried out at a very high temperature, the prior addition of triethylene glycol can allow sufficient reflux for the required completion time without evaporating the solvent fully.
Furthermore, Luminol is an organic compound used to detect metallic ions in Biology. For example, it is used to detect blood traces in forensic investigations.

Explanation:
The answer is Thickness of solution.
The Beer-Lambert Law equation has the following form:
A=E×b×c
Where A is absorbance, E <span>is the molar absorbtivity, </span>b is the path length of the sample and c <span>is the concentration of the compound in solution.
</span>
<span>Lamber-Ber's law shows that the absorbance of a solution is directly proportional to the concentration of the species to be absorbed, as well as the length of the path. For example, if the length of the path is constant, the UV / VIS spectroscopy can be used to determine the concentration of the absorbent substance in the solution.</span>
