Answer:
pOH = 13.246
Explanation:
pH = -log[H+]
[H+] = [HBr] porque HBr es un acido fuerte.
pH = -log(0.176) = 0.754
pH + pOH = 14
pOH = 14 - 0.754 = 13.246
Physical, because the ice is only changing it's state. It's not changing to a new substance.
When a substance goes from being a liquid to a gas it evaporates, or boils away. Think of boiled eggs.
It's adenosine triphosphate !
