In the ray diagram, a ray refracts at point O. If the line PQ separates two transparent media, which statement BEST describes it?

A) Ray AO is the incident ray, and OB is the normal.
B) Ray OB is the incident ray, and AO is the normal.
C) Ray AO is the incident ray, and OB is the refracted ray.
D) Ray OB is the incident ray, and AO is the refracted ray.

Predict the products of the following acid-base reactions, and predict whether the equilibrium lies to the left or to the right of the reaction arrow.part ao2-(aq)+h2o(l)< => express your answer as part of a chemical equation. identify all of the phases in your answer.o2-(aq)+h2o(l) < => oh-(aq)+oh-(aq)part bpredict whether the equilibrium lies to the left or to the right of the equation in previous part.h2o is a stronger acid than oh–, so the equilibrium lies to the right.h2o is a weaker acid than oh–, so the equilibrium lies to the left.h2o is a stronger acid than oh–, so the equilibrium lies to the left.h2o is a weaker acid than oh–, so the equilibrium lies to the right.part cch3cooh(aq)+hs?

Is this correct if not can u correct me
