Determine the balanced equation for the reaction that occurs when ethylene glycol, C2H4(OH)2C2H4(OH)2, burns in air.

C₂H₄(OH)₂ + 2.5 O₂ ⇒ 2 CO₂ + 3 H₂O

Explanation:

Let's consider the reaction when ethylene glycol burns in air.

C₂H₄(OH)₂ + O₂ ⇒ CO₂ + H₂O

This is a complete combustion reaction in which ethylene glycol reacts with oxygen to form carbon dioxide and water.

First, we will balance the hydrogen atoms.

C₂H₄(OH)₂ + O₂ ⇒ CO₂ + 3 H₂O

Then, we will balance the carbon atoms.

C₂H₄(OH)₂ + O₂ ⇒ 2 CO₂ + 3 H₂O

Finally, we will balance the oxygen atoms.

C₂H₄(OH)₂ + 2.5 O₂ ⇒ 2 CO₂ + 3 H₂O
