Answer: The given reaction represents a combustion reaction.

Step-by-step explanation:

Decomposition reaction is defined as the chemical reaction in which a single substance breaks down into two or more simpler substances.


AB\rightarrow A+B

Combination reaction is defined as the reaction in which two or more smaller substances combine to form a single large substance.


A+B\rightarrow AB

Combustion reaction is defined as the reaction in which a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water.


C_xH_y+O_2\rightarrow CO_2+H_2O

A double displacement reaction is defined as the reaction in which exchange of ions takes place.


AB+CD\rightarrow AD+CB

A single displacement reaction is defined as the reaction in which a more reactive element displaces a less reactive element from its chemical reaction. The reactivity of metal is determined by a series known as reactivity series.


AB+C\rightarrow CB+A

Metal C is more reactive than metal A.

For the given chemical reaction:


2C_2H_2+5O_2\rightarrow 4CO_2+2H_2O

This is considered as a combustion reaction because ethene reacts with oxygen gas to produce carbon dioxide and water molecule.
