Describe combustion reactions in terms of slow, spontaneous and explosive reactions, give examples?

Question

i searched a lot but couldn't find a clear answer. Help would be appreciated.

Answer 1

Slow combustion: coal burning, especially a dense coal such as anthracite.

Spontaneous combustion: the burning of white phosphorus in air (silane and phosphine also combust spontaneously in air - the word for this property is "pyrophoric").

Explosive combustion:  Most modern explosives contain their own oxygen in the molecule, and the explosion is classed as a decomposition rather than a combustion reaction.  However, fuel-air explosives (and the more modern thermobaric weapons) are examples of explosive combustion - a cloud of fuel is dispersed into air and ignited.  The mixing of reactants allows the fuel to burn much more quickly than it would normally (say, in a puddle on the ground).
