Answer:
Equilibrium concentrations of the gases are



Explanation:
We are given that for the equilibrium

Temperature, 
Initial concentration of



We have to find the equilibrium concentration of gases.
After certain time
2x number of moles of reactant reduced and form product
Concentration of



At equilibrium
Equilibrium constant
![K_c=\frac{product}{Reactant}=\frac{[H_2]^2[S_2]}{[H_2S]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7Bproduct%7D%7BReactant%7D%3D%5Cfrac%7B%5BH_2%5D%5E2%5BS_2%5D%7D%7B%5BH_2S%5D%5E2%7D)
Substitute the values



By solving we get

Now, equilibrium concentration of gases



The species that represents an ion is B³+ (option A).
<h3>What is an ion?</h3>
An ion is an atom or group of atoms bearing an electrical charge, such as the sodium and chlorine atoms in a salt solution.
Simply put, an ion is said to be an electrically charged atom. This refers to the difference in the number of protons and electrons in the atom of an element.
According to this question, the species with an electrical charge is B³+, hence, it represents an ion.
