<span>The answer is melting and freezing point. At the melting point the solid and liquid stage occur in equilibrium. The melting point of a material hinge on pressure and is typically quantified at standard pressure. When measured as the temperature of the opposite alteration from liquid to solid, it is denoted as the freezing point.</span>

Answer:
9.62moles of NH₃
Explanation:
Given parameters:
Number of moles of nitrogen = 4.81moles
Unknown:
Number of moles of NH₃ = ?
Solution:
To solve this problem, we need to establish a balanced reaction equation:
N₂ + 3H₂ → 2NH₃
Now, we can solve the problem by working from the known to the unknown.
1 mole of N₂ produced 2 moles of NH₃
4.81moles of N₂ will produce 2 x 4.81 = 9.62moles of NH₃
Answer:
will form a precipitate of insoluble 
when aqueous 
is added.
Explanation:
According to solubility rule-
all carbonates are insoluble except group IA compounds and 
all salts of sodium are soluble
When is added to given solutions, a double displacement reaction takes place in each solution to form a sodium salt and a carbonate salt.
So, in accordance with solubility rule, addition of into will result precipitation of insoluble
Reaction:
