Wood is mainly cellulose, a polymer produced by plants. One use of wood is as a fuel in campfires, fireplaces, and wood furnaces. The molecules of cellulose are tong chains of repeating units. Each unit of the chain can be represented as C.HOs. The balanced equation below represents a reaction that occurs when C.HOs is burned in air.

C6H1005 + 0₂ → CO₂ + H₂O + heat

5. Balance the chemical equation using the smallest whole number coefficient.
