What reaction type is depicted by the following equation? 2c2h2 + 5o2 4co2 + 2h2o decomposition combination combustion single-replacement double-replacement

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

The given reaction represents a combustion reaction.

Explanation:

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

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

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

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

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.

Metal C is more reactive than metal A.

For the given chemical reaction:

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