Answer:

CH₃OH + 1.5 O₂ ⇒ CO₂ + 2 H₂O

Explanation:

Let's consider the unbalanced chemical equation for the complete combustion of methanol.

CH₃OH + O₂ ⇒ CO₂ + H₂O

We will balance it using the trial and error method.

First, we will balance H atoms by multiplying H₂O by 2.

CH₃OH + O₂ ⇒ CO₂ + 2 H₂O

Finally, we get the balanced equation by multiplying O₂ by 1.5.

CH₃OH + 1.5 O₂ ⇒ CO₂ + 2 H₂O
