Ответ:
a. CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
Explanation:
En la representación que tienes en la imagen puedes observar que el átomo de carbono es el que está de color negro, los átomos de hidrógeno están de color gris y los átomos de oxígeno de color rojo.
En la reacción, 1 molécula de CH₄ reacciona con 2 moléculas de O₂ produciendo 1 molécula de CO₂ (Un átomo de carbono y dos de oxígeno) y dos moléculas de agua (H₂O, un átomo de oxígeno y dos de hidrógeno).
Así, la reacción correctamente balanceada es:
a. CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)
