Answer:
Kc = 826
Explanation:
For the equilibrium:
8 H₂S (g) ⇄ 8 H₂(g) + S₈ (g)
the equilibrium constant is:
Kc = [ H₂ ] ⁸ x [ S₈ ] / [H₂S]⁸
Kc = 0.600⁸ x 0.750 / (0.250)⁸ = 1.68 x 10⁻² x 0.750 / 1.53 x 10⁻⁵
= 824
Be careful with raising to the power of 8 in your calculator.

Answer:
A neutralization reaction between an acid and a metal hydroxide produces salt and water.
Explanation:
In a neutralization reaction, an acid and a base are combined according to the following example (hydrochloric acid and sodium hydroxide):
HCl + NaOH ---> H20 + NaCl
They are generated as products: water and a salt, in this case sodium chloride.
Answer:
AgCl + NaNO3 would be the products of the reaction between sodium chloride and silver nitrate.
The stoichiometry of this reaction is written below, and it is because for this reaction to be fulfilled the products have to be in equilibrium with the reactants, since the mass in the reaction is conserved and must be balanced in the amount of molecules that they react to each other.
Explanation:
NaCl + AgNO3 -------------- AgCl + NaNO3
