Question 20.4

Write the balanced chemical equation for the following reaction and identify the type of reaction:

Ethanol is burnt in air to form carbon dioxide, water and releases heat.

Answer 1

Given below is the chemical equation for the given reaction:

${\text{C}}_2{\text{H}}_5\text{OH(l)}+3{\text{O}}_2\text{(g)}\to 2{\text{CO}}_2\text{(g)}+3{\text{H}}_2\text{O(l)}+\text{Heat}$

It is a combustion reaction as ethanol is reacting with oxygen to give carbon dioxide, water and heat.
