Explanation:
They share 2 electrons with carbon.
<h3><u>Answer;</u></h3>
Ka == 1.153 × 10^-4
<h3><u>Explanation</u>;</h3>
Weak acid is HA;
Equilibrium: HA(aq) + H2O(l) <=> H3O^+(aq) + A^-(aq)
Ka = [H3O^+][A^-]/[HA]
[H3O^+] = [A^-] = (0.0125)(0.738)
= 0.00923 M and [HA]
= 0.738 M - 0.00923 M = 0.738 M because the value 0.00923 is insignificant in this case.
Ka = (0.00923)^2/(0.738)
<u>= 1.153 × 10^-4</u>
