The above chemical equation represents the reaction process between calcium oxide (CaO) and carbon (C) to produce calcium (Ca) and carbon monoxide (CO).
-
Reaction conditions: The reaction will occur at high temperature and high pressure.
-
Reaction process: When calcium oxide (CaO) is heated in a carbon furnace (C), it will react with carbon to form calcium and carbon monoxide. The reaction is carried out in a metallurgical furnace or a blast furnace.
-
Phenomenon occurs: During the reaction process, heat is released and carbon monoxide (CO) gas will escape. If the reaction is performed in a closed environment, CO can be dangerous because it is poisonous and can cause suffocation. The product calcium will be in solid form under high temperature and pressure conditions.
