The answer is: supersaturated solution.
A supersaturated solution contains more of the dissolved substance than could be dissolved by the solvent under normal circumstances.
A way to dissolve more sugar into a solution is heating a solution.
The more heat is added to a system, the more soluble a substance (in this example sugar) becomes.
The solution will become supersaturated if this solution is suddenly cooled at a rate faster than the rate of precipitation.
Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
<h3>What is thermal equilibrium?</h3>
The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.
Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.
In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.

Explanation:
It is given that the total volume is (10 mL + 60 mL) = 70 mL.
Also, it is known that 
= 
Where, 
= total volume
= initial volume
Therefore, new concentration of 
= 
= 
= 0.43 M
New concentration of NaOH =
= 
= 0.14 M
So, the given reaction will be as follows.
Initial: 0.43 0.14 0
Change: -0.14 -0.14 0.14
Equilibrium: 0.29 0 0.14
As it is known that value of 
= 4.74
Therefore, according to Henderson-Hasselbalch equation calculate the pH as follows.
pH = ![pK_{a} + log \frac{[CH_{3}COO^{-}]}{[CH_{3}COOH]}](https://tex.z-dn.net/?f=pK_%7Ba%7D%20%2B%20log%20%5Cfrac%7B%5BCH_%7B3%7DCOO%5E%7B-%7D%5D%7D%7B%5BCH_%7B3%7DCOOH%5D%7D)
= 
= 4.74 + (-0.316)
= 4.42
Therefore, we can conclude that the pH of given reaction is 4.42.
Answer:
ur correct. except for type of reaction is Exothermic
Explanation:
im a teacher!
Each mole of N₂ generates 2 moles of Li₃N. Thus,
0.08 moles of Li₃N will require:
0.08 / 2
= 0.04 moles of N₂
The second option is correct.
