dezieAs the wood burns, it produces different compounds depending on the temperature used. Some studies cite calcium carbonate (Templeeti:Chem) as the major constituent, others find no carbonate at all but calcium oxide (Templeeti:Chem) instead. The latter is produced at higher temperatures (see calcination).[2] The equilibrium reaction CaCO3 → CO2 + CaO has its equilibrium shifted leftward at Lua error in package.lua at line 80: module 'Module:Convert/data' not found. and high Templeeti:CO2 partial pressure (such as in a wood fire) but shifted rightward at Lua error in package.lua at line 80: module 'Module:Convert/data' not found. or when Templeeti:CO2 partial pressure is reduced.
