Given an equilibrium constant value of 7.2 x 10-4 it is false to say that the reaction proceeds essentially to completion.
<h3>What is the equilibrium constant?</h3>
In a reaction, we can judge using the value of the equilibrium constant weather or not the reaction moves on to completion. If the reaction moves up to completion, it the follows that the value of the equilibrium constant ought to be large.
On the other hand, when we have a case that the equilibrium constant is small and is not so large, then the reaction does not proceed essentially to completion.

Answer:
pH = 1.33
Explanation:
Because HCl is a strong acid, each mole of HCl will completely dissociate into H⁺ and Cl⁻ species.
Now we calculate the molar concentration (molarity) of H⁺:
- Molarity = moles / volume
(750 mL ⇒ 750 / 1000 = 0.750 L)
- Molarity = 0.035 moles / 0.750 L
Then we calculate the pH of the solution:
The sun is a star.

Answer : The reactant acid and conjugate base in this reaction is, 
and 
.
Explanation :
Conjugate acid : A species that is formed by receiving of a proton 
by a base is known as conjugate acid.
Conjugate base : A species that is formed by donating of a proton by an acid is known as conjugate base.
The given chemical reaction is,
In this reaction, 
(base) react with (acid) to give 
(conjugate acid) and (conjugate base).
Therefore, the reactant acid and conjugate base in this reaction is, and .
