Answer:D
Explanation:
I’ve had this question before. Since it’s stairs, the potential energy would decrease due to height decrease and it will be transformed to kinetic energy
I'm taking the same quiz. The answer is column
<u>Answer:</u> The concentration of hydrogen gas at equilibrium is 
<u>Explanation:</u>
We are given:
Initial moles of hydrogen sulfide gas = 0.47 moles
Volume of the container = 3.0 L
The molarity of solution is calculated by using the equation:

So, 
The given chemical equation follows:

<u>Initial:</u> 0.1567
<u>At eqllm:</u> 0.1567-2x 2x x
The expression of
for above equation follows:
![K_c=\frac{[H_2]^2[S_2]}{[H_2S]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5E2%5BS_2%5D%7D%7B%5BH_2S%5D%5E2%7D)
We are given:

Putting values in above equation, we get:

So, equilibrium concentration of hydrogen gas = 
Hence, the concentration of hydrogen gas at equilibrium is
