Answer:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)
Step-by-step explanation:
- To obtain the overall reaction, we add the two equations and omit the intermediates.
- The intermediate is the reaction species that appeared in one step and consumed in the following steps.
- The intermediate here is H₂O(g) that appears in the first step and has been consumed in the second step.
So, the overall reaction is: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l)
