What type of reaction is CH4 + 2 O2 -> CO2 + 2 H2O?

Explanation:
Combustion of a hydrocarbon with oxygen to form carbon dioxide and water. This reaction fits the classic pattern of a fuel reacting with O2 to produce CO2 and H2O, with an overall release of energy. The equation shows methane reacting with oxygen to yield carbon dioxide and water, which is the hallmark of combustion (oxidation). It isn’t synthesis because you’re not building one product from elements; you’re forming two products. It isn’t decomposition because a single compound isn’t breaking apart. It isn’t single displacement because nothing is replacing an element in a compound; oxygen simply adds and oxidizes the fuel.
