Answer:
the answer is either B or C
explanation:
brainliest?
Answer:
Leon
Explanation: all take up space and will have a mass to it.
What is the relationship between wavelength, frequency and energy? The energy of a wave is directly proportional to its frequency, but inversely proportional to its wavelength. In other words, the greater the energy, the larger the frequency and the shorter (smaller) the wavelength.
Answer:
Therefore the equilibrium constant
is 9.35× 10²⁵
Explanation:
Equilibrium constant:
Equilibrium constant is used to find out the ratio of the concentration of the product to that of reactant.
xA+yB→zC
The equilibrium constant K,
![k=\frac{[C]^z}{[A]^x[B]^y}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B%5BC%5D%5Ez%7D%7B%5BA%5D%5Ex%5BB%5D%5Ey%7D)
Here [A] is equilibrium concentration of A
[B] is equilibrium concentration of B
[C] is equilibrium concentration of C.
1.

![K_1=\frac{[HS^-][H^+]}{[H_2S]}](https://tex.z-dn.net/?f=K_1%3D%5Cfrac%7B%5BHS%5E-%5D%5BH%5E%2B%5D%7D%7B%5BH_2S%5D%7D)
2.

![K_2=\frac{[S^{2-}][H^+]}{[HS^-]}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BS%5E%7B2-%7D%5D%5BH%5E%2B%5D%7D%7B%5BHS%5E-%5D%7D)
3.

![K_3=\frac{[H_2S]}{[S^{2-}][H^+]^2}](https://tex.z-dn.net/?f=K_3%3D%5Cfrac%7B%5BH_2S%5D%7D%7B%5BS%5E%7B2-%7D%5D%5BH%5E%2B%5D%5E2%7D)
Therefore,
![k_1k_2=\frac{[HS^-][H^+]}{[H_2S]}\frac{[S^{2-}][H^+]}{[HS^-]}](https://tex.z-dn.net/?f=k_1k_2%3D%5Cfrac%7B%5BHS%5E-%5D%5BH%5E%2B%5D%7D%7B%5BH_2S%5D%7D%5Cfrac%7B%5BS%5E%7B2-%7D%5D%5BH%5E%2B%5D%7D%7B%5BHS%5E-%5D%7D)
![\Rightarrow k_1k_2=\frac{[S^{2-}][H^+]^2}{[H_2S]}](https://tex.z-dn.net/?f=%5CRightarrow%20k_1k_2%3D%5Cfrac%7B%5BS%5E%7B2-%7D%5D%5BH%5E%2B%5D%5E2%7D%7B%5BH_2S%5D%7D)



⇒K₃=9.35× 10²⁵
Therefore the equilibrium constant
is 9.35× 10²⁵
