Morphology

peroxide = oxide (semi-transparent) = per + oxide

The structure 'per-' + 'oxide' is clear, but 'per-' is a specialized chemistry prefix indicating a particular oxygen-rich/oxygen–oxygen structure, so learners may not infer the precise chemical meaning from the components.

Etymology

Peroxide comes from the parts per- ('extra') and oxide (from 'oxygen'). So peroxide really means 'extra oxygen', and that extra oxygen is what lets it bleach things and kill germs.
