Consider the following intermediate chemical equations.
mixas84 [53]

Answer:

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).

Explanation:

  • We have two equations:

CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g)

2H₂O(g) → 2H₂O(l)

  • To add the two equations: we omit H₂O(g)  that is formed by 2 moles in the product side of the first equation and consumed by 2 moles from the reactants side in the second equation

  • So, the overall chemical equation is obtained by combining these intermediate equations is:

<em>CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l).</em>
