Question

What reaction type is depicted by the following equation? 2C2H2 + 5O2 4CO2 + 2H2O decomposition combination combustion single-replacement double-replacement

Answer 1

combustion is when you burn something in presence e of oxygen and the products will be mainly the CO2 and H2O

Answer 2

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.
