Applying the Law of Conservation of Mass, balance this equation:

CH₄ + O₂ → CO₂ + 2H₂

• CH₄ + O → CO₂ + 2H₂O₂

• CH₄ + 2O → CO₂ + 2H₂O

• CH₄ + 2O₂ → CO₂ + 2H₂O

• CH₄ + O → CO₂ + H₂O₂

Choose the answer that shows this equation balanced

N₂ + O₂ ----> N₂O₅

• 3N₂ + O₂ ----> 3N₂O₅

• 2N₂ + 5O₂ ----> 2N₂O₅

• 5N₂ + 2O₂ ----> 5N₂O₅

• 8N₂ + 2O₂ ----> 8N₂O₅
