Oxidizer 16
Oxidizer 16 : The oxidizer is the other reactive of the chemical reaction. In most cases, it is the ambient air, and in particular one of its components, Oxygen (O2). By depriving a fire of air, we extinguish it; for example, when covering the flame of a small candle with an empty glass, fire stops; to the contrary, if we blow over a wood fire, we activate it (by bringing more air). In certain torches, we bring dioxygen to improve combustion. In certain cases such as some explosives, the oxidizer and combustible are the same (e. g. , nitroglycerin, an unstable molecule that has oxidizing parts in the same molecule as the oxidizeable parts). Reaction is initiated by an activating energy, in most cases, it is heat. Several examples include friction, as in case of matches, heating an electrical wire, a flame (propagation of fire), or a spark (from a lighter or from any starting electrical device). There are also many other ways to bring sufficient activation energy including electricity, radiation, and pressure, all of which will lead to a temperature rise. In most cases, heat production enables self-sustainability of the reaction, and enables a chain reaction to grow. The temperature at which a liquid produces sufficient vapor to get a flammable mix with self-sustainable combustion is called its flash-point
