Question

Differentiate between spontaneous and explosive combustion

Answer 1

spontaneous combustion:

The combustion in which substances suddenly burst into flames, without the application of any apparent cause is called spontaneous combustion.

For example, sodium and phosphorus burn spontaneously in air, even when no external heat is provided to them.

explosive combustion:

The combustion in which sudden reactions take place on ignition of some substances to produce heat, light, and sound is called explosion.

For example, fireworks on ignition produce heat, light, and sound.

hope it helps pls mark it as brainliest please..

Answer 2

Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.

Explosive Combustion Reactions. Explosive combustion reactions involve not only a reaction with oxygen, but also a chemical that promotes oxidation (oxidizing agent). Because of this, the reaction is not limited by the amount of oxygen present and can occur quickly. The result is, well, explosive.
