D
CO
Verified step by step guidance1
Understand that complete combustion of a hydrocarbon like methane (CH_4) involves reacting it with oxygen (O_2) to produce carbon dioxide (CO_2) and water (H_2O).
Write the balanced chemical equation for the complete combustion of methane: \(\mathrm{CH_4 + 2\ O_2 \rightarrow CO_2 + 2\ H_2O}\).
Identify the products on the right side of the equation, which are carbon dioxide (CO_2) and water (H_2O).
Recognize that incomplete combustion can produce carbon monoxide (CO) or other hydrocarbons, but complete combustion specifically produces carbon dioxide (CO_2).
Conclude that among the given options, \(\mathrm{CO_2}\) is the correct product formed during the complete combustion of methane.
