Which substances are known to contain oxidizers?

Oxidizers are substances that can cause or enhance the combustion of materials by providing oxygen or other oxidizing agents during a chemical reaction. Organic compounds can sometimes act as oxidizers, particularly when they have functional groups that can donate oxygen or react with oxygen in the presence of heat or flame. Peroxides are well-known oxidizing agents due to their unstable nature and ability to release oxygen, which can significantly increase the likelihood of combustion.

The presence of organic compounds and peroxides makes this answer relevant, as both categories can facilitate combustion and are typically found in various chemical processes and burning scenarios. Other options include substances or mixtures that do not primarily act as oxidizers. For instance, water is used to extinguish fires rather than support combustion, and salt is generally stable without oxidizing properties. Oil and vinegar, while combustible, do not behave as oxidizers, but rather as fuels. While hydrogen and oxygen together can produce a combustible mixture, hydrogen itself is a fuel, and oxygen is the source of oxidation but not to be classified simply as an oxidizer. Thus, the combination of organic compounds and peroxides distinctly aligns with the characteristics of oxidizing agents.
