This reaction is highly exothermic, producing the prodigious explosion.Pop sound indicates that the presence of a combustible gas which immediatelt catches fire as soon as it comes in contact with the fire. the gas could be hydrogen also as it is also very combustible gas.

Chemical Reaction of Hydrogen burning :

$2H_{2} + O_{2} → 2H_{2}O +energy$
