Answer:
6.59.
Explanation:
∵ pOH = - log[OH⁻]
<em>∴ pOH = - log[OH⁻]</em> = - log(3.9 x 10⁻⁸) = <em>7.408.</em>
∵ pH + pOH = 14.0.
<em>∴ pH = 14.0 - pOH </em>= 14.0 - 7.408 = <em>6.59.</em>
Entropy is positive as liquids have greater disorder in terms of arrangement than that of solid ( use your entropy explanation for this) the Gibbs free energy change is positive as the reaction is spontaneous

1L of hot water just below the Boling point
Explanation:
asking questions is best to learn please ask more questions
Both carbon and lead belong to Group IV elements, and thus they have the same number of valence electrons.
<span>In each of the other options, the two elements belong to different groups, and thus they do NOT have the same number of valence electrons.</span>
