Ethanol burns to release energy. Which reaction shows this reactio

The reaction that shows the burning of ethanol to release energy is:

C2H5OH (l) + 3O2 (g) → 2CO2 (g) + 3H2O (l)

Here's the step-by-step process:

1. Ethanol (C2H5OH) reacts with oxygen (O2) in the air. This is the reactant side of the equation.

2. The reaction is a combustion reaction, which means it burns in the presence of oxygen to produce heat and light energy.

3. The products of this reaction are carbon dioxide (CO2) and water (H2O).

4. The balanced chemical equation shows that for every one molecule of ethanol, three molecules of oxygen are required to produce two molecules of carbon dioxide and three molecules of water.

5. The reaction is exothermic, meaning it releases energy in the form of heat and light.
