I believe a possible Lewis dot structure that does not obey the octet rule, where all elements are required to have 8 electrons in their outermost shell, would be the SF4 molecule.
Sulfur can contain an more than 8 electrons, in this molecule and thus has an expanded octet.
I’m not 100% sure but I think it’s convection
Symbol: Hg
Made of hydrargyrum
Atomic number: 80
Atomic weight: 200.59
Poor conductor if heat and an ok conductor for electricity. Primarily used for many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents.
Hope it helps!
It's called "Ionic compound"
Answer:
[PCl₃] = 0.031M
[Cl₂] = 0.031M
[PCl₅] = 0.969M
Explanation:
Based on the reaction:
PCl₅(g) ⇄ PCl₃(g) + Cl₂(g)
Keq is defined as:
<em>Keq = 1.0x10⁻³ = [PCl₃] [Cl₂] / [PCl₅]</em>
<em>Where [] are equilibrium concentrations of each species</em>
Inital [PCl₅] = 2.0mol / 2.0L = 1M.
In equilibrium:
[PCl₃] = X
[Cl₂] = X
[PCl₅] = 1M-X
Where X is reaction coordinate
Solving for X in Keq:
1.0x10⁻³ = [X] [X] / [1-X]
1.0x10⁻³ - 1.0x10⁻³X = X²
1.0x10⁻³ - 1.0x10⁻³X - X² = 0
X:
X = -0.032M. False solution, there is no negative concentration
X = 0.031M
That means equlibrium concentrations are:
[PCl₃] = 0.031M
[Cl₂] = 0.031M
[PCl₅] = 1-0.031M = 0.969M
<h3>[PCl₃] = 0.031M</h3><h3>[Cl₂] = 0.031M</h3><h3>[PCl₅] = 0.969M</h3>
