Write the chemical equation of the reaction which takes place on burning ethanol in oxygen.

Explanation

To write the chemical equation for the combustion of ethanol in oxygen, follow these steps:

### Step 1: Write the Reactants
The reactants in this reaction are ethanol (C2H5OH) and oxygen (O2).

### Step 2: Write the Products
When ethanol burns in oxygen, it produces carbon dioxide (CO2) and water (H2O). The general reaction can be written as:
\[ \text{C}_2\text{H}_5\text{OH} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} + \text{heat} \]
