That it is below the lithosphere and it is the remainder of the mantle or lower mantle
Answer:
(A) 
Solubility will increase.
(B) 
Solubility will decrease.
(C) 
Solubility will decrease.
Explanation:
a) According to Le Chatelier's Principle when a change is introduced in a reaction system at equilibrium, the system responds by the reaction shifting in the direction to counter the change introduced.
When the change introduced is addition of acid, some 
are consumed due to it and the system would respond by reaction shifting towards creation of more in the system by increased dissolution. Thus solubility increase.
(b) When are added, the reaction shifts to counter the change introduced of increased by shifting to side that decreases the increased . That happens by reaction shifting towards some 
precipitating back. Hence solubility decreases.
(c) The change introduced is addition of 
which will be countered by reaction shifting to side that decreases increased 
, which happens by some 
precipitating back. Hence solubility decreases.

Answer:
44.8 L of N₂.
Explanation:
We'll begin by writing the balanced equation for the. This is illustrated below:
N₂ + 3H₂ —> 2NH₃
From the balanced equation above,
1 mole of N₂ reacted to produce 2 moles of NH₃.
Therefore, Xmol of N₂ will react to produce 4 moles of NH₃ i.e
Xmol of N₂ = (1 × 4)/2
Xmol of N₂ = 2 moles
Thus, 2 moles of N₂ reacted to produce 4 moles of NH₃.
Finally, we shall determine the volume of N₂ required for the reaction. This can be obtained as follow:
1 mole of N₂ occupies 22.4 L at STP.
Therefore, 2 moles of N₂ will occupy = (2 × 22.4) = 44.8 L
Thus, 44.8 L of N₂ is needed to produce 4 moles of NH₃.
