Question
Chapter 6, Problem 4QAP
Interpretation Introduction
Interpretation:
The role of hydrogen peroxide in small cuts and abrasions should be explained.
Concept Introduction:
Chemical change requires a change in bonding between atoms. It is typically accompanied by change in color, odor, physical state, oxidation number, etc. In a chemical change, the new compound is formed and the compound undergoing a chemical change loses its identity.
