Write an equilibrium expression for each chemical equation involving one or more solid or liquid reactants or products.

Alex_Xolod [135]

Answer:

$Keq=\frac{[HCO_3^-][OH^-]}{[CO_3^{2-}]}$

$Keq=[O_2]^3$

$Keq=\frac{[H_3O^+][F^-]}{[HF]}$

$Keq=\frac{[NH_4^+][OH^-]}{[NH_3]}$

Explanation:

Hello there!

In this case, for the attached reactions, it turns out possible for us to write the equilibrium expressions by knowing any liquid or solid would be not-included in the equilibrium expression as shown below, with the general form products/reactants:

$Keq=\frac{[HCO_3^-][OH^-]}{[CO_3^{2-}]}$

$Keq=[O_2]^3$

$Keq=\frac{[H_3O^+][F^-]}{[HF]}$

$Keq=\frac{[NH_4^+][OH^-]}{[NH_3]}$

Regards!
