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;
.

If x represents the mass of 1 ball in kg, then the balance shows ...
... 6x = x + 9 kg
... 5x = 9 kg
Then 6x is ...
... (6/5)·5x = (6/5)·9 kg = 10.8 kg
0.8 kg = 0.8·1000 g = 800 g
so 10.8 kg is ...
... D. 10 kg 800 g
$14.52 because $20 - $5.48 = 14.52
12/h is what you need to write down if you don’t know what h is
Sec 2 A = 1 / cos 2 A
1 / cos 2 A = 1 / sin 13 A
cos 2 A = sin 13 A
2 A = 90° - 13 A
2 A + 13 A = 90°
15 A = 90°
A = 90° : 15
Answer:
B ) A = 6°
