How are explosions different from other chemical reactions?

Answer 1

Yes, combustion is a chemical reaction, because it is a reaction between a molecule and oxygen (O2) to produce a new molecule plus CO2 (if it's a complete combustion) or CO (if it is an incomplete combustion). Combustion is also an exothermic reaction, which means that heat is released.

Answer 2

Decomposition reactions differ from combustion reactions because a combustion

reaction is an exothermic reaction in which the substance combines with oxygen, and a decomposition reaction is when a substance is broken down into simpler substances.

Answer 3

The short answer is combustion reactions are a subset of synthesis reactions that require one of the reactants to be oxygen. Common combustion of organic molecules results in the formation of CO2 . However, it is not required that combustion be limited to organic molecules. They are different from decomposition reactions in the same way synthesis is the opposite of decomposition.

Answer 4

A decomposition reaction turns molecules into smaller molecules (or even atoms). Examples of decomposition reactions are electrolyses, photolysis, thermolysis (and many more).

Whereas a combustion reaction combines molecules (such as methane) with oxygen to form other molecules (in this case, CO2 and H2O)

So to sum it up.

Decomposition

AB --> A + B

Combustion

AB + O2 --> AO + BO

Answer 5

Combustion contains explosive force where chemical reactions are not always such.

Answer 6

Explosions are just very fast violent chemical reactions. Nuclear fission causes an explosion; oxidation of methane can be considered almost an explosion.

Answer 7

Yes, it is. The molecule itself changes here. Complete combustion results in the formation of carbon dioxide from the starting fuel (i.e. organic matter).

Answer 8

Because combustion is an oxidation reaction.

Answer 9

A combustion reaction is only a reaction with oxygen (oxidation).
A composition reaction is more general, it is a reaction involving reactants to obtain products.
