Oxygen: the comburent par excellence; involved in the vast majority of flammable and explosive reactions. The redox reactions in which it is involved generate energy, carbon dioxide, and water.
Ozone: a gaseous molecule whose oxidizing power has wide applications in water purification processes.
Hypochlorites: unstable ions that decompose in sunlight and in the presence of heat.
Peroxyacetone (acetone peroxide): a highly unstable organic compound that reacts easily to heat, friction, or impact.
