Answer 2

Answer: The balanced chemical equation is given below.

Explanation:

Ethanol is a hydrocarbon because a covalent bond is present between hydrogen and carbon atom.

When a hydrocarbon is burnt in air, it results in the formation of carbon dioxide and water molecule. This reaction is known as combustion reaction.

The chemical equation for the reaction of combustion of ethanol follows:

$CH_3CH_2OH+3O_2\rightarrow 2CO_2+3H_2O+\text{ heat}$

By Stoichiometry of the reaction:

1 mole of ethanol reacts with 3 moles of oxygen to produce 2 moles of carbon dioxide and 3 moles of water molecule.
