Ngwakọta kemịkal 
As the wood burns, it produces different compounds depending on the temperature used. Some studies cite calcium carbonate () as the major constituent, others find no carbonate at all but calcium oxide () instead. The latter is produced at higher temperatures (see calcination). The equilibrium reaction CaCO3 → CO2 + CaO has its equilibrium shifted leftward at  and high  partial pressure (such as in a wood fire) but shifted rightward at  or when  partial pressure is reduced.
