Answer:
n = 3.0 moles
V = 60.0 L
T = 400 K
From PV = nRT, you can find P
P = nRT/V = (3.0 mol)(0.0821 L-atm/K-mol)(400 K)/60.0L
P = 1.642 atm = 1.6 atm (to 2 significant figures)
Explanation:
A. The reaction would remain in equilibrium
<h3>Further explanation</h3>
Given
Reaction
H₂ + I₂ ⇔ 2HI
Required
the effect of pressure changes
Solution
In the equilibrium system :
<em>Reaction = - action
</em>
⇒shift the reaction to the right or left.
The pressure usually affects the gas equilibrium system(only count the number of moles of gases)
The addition of pressure, the reaction will shift towards a smaller reaction coefficient ((the fewest moles of gas )
Reaction
H₂ + I₂ ⇔ 2HI
The reactant side of the equation has 2 moles of a gas(1 mole H₂ and 1 mole I₂) ; the product side has 2 moles HI
So the total number of moles from both sides is the same(2 moles) so that the change in volume (pressure) <em>does not change the direction of equilibrium⇒No shift will occur
</em>
Sorry I can't tell you the answer but, I can tell you something...
Dividing the mass of the water lost by the mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
How to find it?
Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical actual percent hydration percent water can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.

Explanation:
Some genetic mutations, like being able to drink milk are beneficial. While others, like sickle cell anemia. I know you didn’t ask, but it’s just for future reference.
