Answer: When an inert gas is added to the system in equilibrium at constant pressure, then the total volume will increase.
Explanation:
<span>Using a mixture of water, sand, and chemicals under high pressure to free tightly held oil and natural gas is known as Hy</span>draulic fracturing.
<span>
This is a process commonly practiced in the United states where millions of gallons of water, sand, and chemicals are pumped underground. This is used to break apart the rock bed and release the gases that are deep in the ground.</span>
Answer:
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
Explanation:
Given data:
Number of moles of hydrogen react = 4.0 mol
Number of moles of ammonia produced = ?
Solution:
Chemical equation:
N₂ + 3H₂ → 2NH₃
Now we will compare the moles of hydrogen and ammonia from balance chemical equation.
H₂ : NH₃
3 : 2
4 : 2/3×4 = 2.67 mol
From 4.0 moles of hydrogen 2.67 moles of ammonia are produced.
A "3" should but put in front of

M(NaOH)=15 g
v=600 ml=0.6 l
n(NaOH)=m(NaOH)/M(NaOH)
C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]
C=15g/[40g/mol*0.6 l]=0.625 mol/l
0.625M
[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875
