@freemo It makes H2O and CO2 because it is also combustion.
@AmpBenzScientist No not necessarily. Not all explosions need to be a combustion and not all explosions produce H2O or CO2. Some do fit that description of course.
@freemo Organic Peroxides deflagragate and are endothermic.
@freemo An energetic decomposition.
@AmpBenzScientist deflagrate just means a chain reaction of heat.. its a broader category than an explosion. Almost anything that burns is deflating. A campfire is deflagration. Its nothing special.
