is the equilibrium constant expression for
NH₂HS(S) → NH₂(g) + H₂S(g). Hence, option A is correct.
<h3>Definition of equilibrium constant.</h3>
A number that expresses the relationship between the amounts of products and reactants present at equilibrium in a reversible chemical reaction at a given temperature.
Equilibrium constant for the NH₂HS(S) → NH₂(g) + H₂S(g) will be:
![K_c = \frac{[Product]^{coefficient}}{[Reactantt]^{coefficient}}](https://tex.z-dn.net/?f=K_c%20%3D%20%5Cfrac%7B%5BProduct%5D%5E%7Bcoefficient%7D%7D%7B%5BReactantt%5D%5E%7Bcoefficient%7D%7D)
![K_c = \frac{[NH_2]^{1}[H_2S]^{1}}{[NH_2HS]^{1}}](https://tex.z-dn.net/?f=K_c%20%3D%20%5Cfrac%7B%5BNH_2%5D%5E%7B1%7D%5BH_2S%5D%5E%7B1%7D%7D%7B%5BNH_2HS%5D%5E%7B1%7D%7D)
Hence, option A is correct.

Answer:
Molar ratio of the compound is 1:1 and the type of hydrate is Mono hydrate.
Explanation:
From the given,
Mass of sodium carbonate
= 8.85 g
Loss mass
= 1.28 g
Actual weight of sodium carbonate = 8.85 g - 1.28 g = 7.57 g


Therefore, the compound has only one water molecule.
Molecular formula of the compound is
an name of the compound is <u>sodium carbonate mono hydrate.</u>
Hence, the type of the compound is Mono hydrate.
Explanation:
B more negative charges than positive charges
Answer:
0.75 cm
