<h2><u>
Answer:</u></h2>
n = 0.0989 moles
<h2><u>
Explanation:</u></h2>
n = PV / RT
P = 2.09atm
V = 1.13L
R = 0.08206
T = 291K
Plug the numbers in the equation.
n = (2.09atm)(1.13L) / (0.08206)(291K)
n = 0.0989 moles
Answer: they have a net positive charge
Explanation:
At first we thought atoms were just electrons and were negatively charged, but now we’ve learned that is can create different and many more substances.
Answer:
[S₂] = 1.27×10⁻⁷ M
Explanation:
2 H₂S(g) ⇄ 2 H₂(g) + S₂(g), Kc=1,625x10⁻⁷
The equation of this reaction is:
1,625x10⁻⁷ = ![\frac{[H_2]^2[S_2]}{[H_{2}S]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH_2%5D%5E2%5BS_2%5D%7D%7B%5BH_%7B2%7DS%5D%5E2%7D)
The equilibrium concentrations are:
[H₂S] = 0,162 - 2x
[H₂] = 0,184 + 2x
[S₂] = x
Replacing:
1,625x10⁻⁷ = ![\frac{[0,184+2x]^2[x]}{[0,162-2x]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B0%2C184%2B2x%5D%5E2%5Bx%5D%7D%7B%5B0%2C162-2x%5D%5E2%7D)
Solving:
4x³ + 0,736x² + 0,033856x - 4,3x10⁻⁹
x = 1.27×10⁻⁷
Thus, concentration of S₂ is:
<em>[S₂] = 1.27×10⁻⁷ M</em>
