Discussion
When Pressure increases equilibrium shifts to the side with the smallest number of moles. But which side is that?
N2(g) + 3H2(g) ⇌ 2NH3(g)
The left side has 1 mol of nitrogen (N2) and 3 moles of Hydrogen = 4 mols
on the left side.
The right side has 2 mols of NH3 = 2 mols on the right.
Conclusion: You tell the number of mols by the Balance numbers to the left of each chemical in an equation.
Since the left side N2 + 3H2 = 4 mols, the equilibrium does NOT shift left.
2NH3 is only two mols.
The equilibrium shifts Right

D
Answer: Gravity
Explanation: The answer is gravity: an invisible force that pulls objects toward each other. ... So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
Answer:
Explanation:
Calculate the pOH for a solution that has a hydroxide ion, (OH-) concentration of 5.02 X 10-4 M.
Calculate the pH.
Note: the answers should have three significant figures
You can tell them apart from its form.
If it forms loose and needs like a container to hold it up, that's liquid.
If it is hard and stable, definitely a solid.
And if you barely see something very loose (and normally goes up), that's liquid.
