Answer:
It is combustion because C2H4 is reacting with O2, and creates CO2 and H2O
The type of chemical reaction which is given in the question is combustion reaction.
Combustion reactions are those reactions in which hydrocarbon will burn in the presence of oxygen and will form water molecules and carbon dioxide gas.
In the given chemical reaction ethene (C₂H₄) is a hydrocarbon which reacts with oxygen gas to produce water (H₂O) and carbon dioxide (CO₂), so the given reaction is combustion reaction.
Hence the given reaction is a combustion reaction.
