The reaction of carbon with oxygen to form carbon dioxide is a combustion reaction. Here's the chemical equation:

C + O₂ → CO₂

* C represents carbon.

* O₂ represents oxygen gas (diatomic oxygen).

* CO₂ represents carbon dioxide.

Explanation:

* When carbon (like charcoal or coal) is heated in the presence of oxygen, it burns.

* This burning process is a chemical reaction where carbon combines with oxygen, releasing energy in the form of heat and light.

* The product of this reaction is carbon dioxide, a colorless and odorless gas.

Important Note:

This reaction is an example of an exothermic reaction, meaning it releases heat into the surroundings. This is why fire produces heat.
