Answer is B
Reason is because H2O and H2o2 are compounds not mixtures. Mixtures are a blend or a combination of two substances through physical means but a compound is formed by two or more substances by chemical means. Now a chemical property basically means the characteristics or quality of a substance that may be observed when it participates in a chemical reaction. They are used to classify chemicals which are used as labels on containers and storage areas. The chemical properties of H2O and H2O2 are different.
