Why is chacoal burning is a chemical change?

Answer 1

Burning the Charcoal changes the chemical composition of it as burning, or combustion as it is known is an example of a chemical reaction.

An example of a combustion reaction is burning Methane (CH4) gas, the chemical equation is:

CH4 + O2 -> CO2 + H2O

The reaction is Methane + Oxygen gives Carbon Dioxide and Water.

The reaction has changed the chemical composition of the Methane as it has 'turned into' Carbon Dioxide and Water.

Burning Charcoal will also produce ONLY Carbon Dioxide and Water.

Hope this helps!

Answer 2

Burning charcoal is a chemical change because it involves a chemical reaction where the charcoal combines with oxygen in the air to form new substances like carbon dioxide and ash. This reaction results in the release of heat and light energy, fundamentally altering the physical and chemical properties of the charcoal.
