Final answer:
The balanced equation for the reaction is CH₄ + 2O₂ → CO₂ + 2H₂O. One molecule of methane (CH₄) reacts with two molecules of oxygen (O₂) to produce one molecule of carbon dioxide (CO₂) and two molecules of water (H₂O).
Step-by-step explanation:
The balanced equation for the reaction is d. CH₄ + 2O₂ → CO₂ + 2H₂O. In this reaction, one molecule of methane (CH₄) reacts with two molecules of oxygen (O₂) to produce one molecule of carbon dioxide (CO₂) and two molecules of water (H₂O). The coefficients in front of each molecule represent the stoichiometric ratio, indicating the number of molecules involved in the reaction.
