How do you balance chemical equations?
stealth61 [152]
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

If the [h+] of a 0.205m solution of phenol (c6h5oh) at 25ºc is 2.340 10-6, what is the ka for phenol? phenol is monoprotic.
Aneli [31]
Answer is: Ka for phenol (C₆H₅OH) is 2.67·10⁻¹¹.
<span>
Chemical reaction: C</span>₆H₅OH(aq) + H₂O(l) → C₆H₅O⁻(aq) + H₃O⁺(aq) or
C₆H₅OH(aq) ⇄ C₆H₅O⁻(aq) + H⁺<span>(aq).
</span>Ka = [C₆H₅O⁻] · [H⁺] / [C₆H₅OH<span>]. 
</span>[H⁺] = [C₆H₅O⁻] = 2.340·10⁻⁶ M; equilibrium concentration.
[C₆H₅OH] = 0.205 M - 2.340·10⁻⁶ M.
[C₆H₅OH] = 0.20499 M.
Ka = (2.340·10⁻⁶ M)² ÷ 0.20499 M.
Ka = 2.67·10⁻¹¹.<span>
