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.
Answer: Lost 3 electrons
Explanation:
Ions are postively or negatively charged atom. The postively charged are called cations while the negativity charged are called anions.
Atom becomes positively charged by losing electrons while negatively charged by gaining electrons.
So, the +3 ion means it has lost 3 electrons
Both sides of the equation would be equal.

Process energy required
1) raise the temperature to 75.0 °C 628 J
2) evaporate the liquid at 75.0°C 15.6 KJ = 15,600 J
3) raise the temperature to ? 712 J
Total energy: 628 J + 15,600 J + 712 J = 16,940 J
As you must have realized the clue to do the problem correctly is to convert all the energy values to joules, because you cant not add up joules with kilo joules.
Answer: 16,940 J
Answer : The molar solubility of in pure water is, 0.0118 M
Explanation : Given,
The solubility equilibrium reaction will be:
Let the molar solubility be 's'.
The expression for solubility constant for this reaction will be,
Now put all the given values in the above expression, we get:
Therefore, the molar solubility of in pure water is, 0.0118 M
