Combustion! CH4, which is methane, reacts with oxygen to form carbon dioxide. (For future reference, if a compound is reacted with ONLY oxygen it is sure to be a combustion reaction)

Answer:

combustion reaction.  

Explanation:

Th given chemical equation is a combustion reaction.  

CH₄ or methane is a hydrocarbon. When a hydrocarbon reacts with oxygen it forms carbon dioxide and water.  

All other options are incorrect.

In a single replacement reaction one element replaces another element in a compound.  

Zn + H₂SO₄ = ZnSO₄ + H₂

In a double replacement reaction the cations of the reactants combines with a different anion of the reactant to form new products.

AgNO₃ + NaCl = AgCl + NaNO₃

In a decomposition reaction a complex molecule is broken down into simple molecules.  

H₂O₂ = 2H₂O + O₂
