Answer:
No, because that would be 4%.
Step-by-step explanation:
400/1000 is 40%, and 40/100 is 40%.
4x and 2x line along a straight line, their sum then must be 180° so
6x=180
x=30
So the angles in there are:
3(30)-5=85°
2(30)=60°
4(30)=120°
The correct equilibrium constant expression for this equation is;

Given
Consider the equation below.

<h3>What are Species?</h3>
In an equilibrium constant expression, you do not include the solid substances; only gases and dissolved substances.
<h3>Equilibrium constant expression;</h3>
It is the quotient of the product of the concentrations of the species on the right-hand side of the equilibrium equation, each raised to its corresponding coefficient, and the product of the concentrations of the species on the left-hand side, each raised to its corresponding coefficient.
Therefore,
The correct equilibrium constant expression for this equation is;

Hence, the correct equilibrium constant expression for this equation is;

Distance southward = 6x = 400, so x=66.66
total distance = 7x+x=8x = 533.33m
