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

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
