The above equation represents the thermal decomposition process of the aluminum oxide compound (Al2O3) into pure aluminum (Al) and oxygen (O2). Accordingly, when 2 moles of Al2O3 decompose, it will produce 4 moles of Al and 3 moles of O2.
- Reaction conditions:
This reaction requires high temperatures (about 2,000 to 3,000 degrees Celsius) to occur.
- Reaction process:
When Al2O3 is heated to high temperatures, the aluminum oxide particles will absorb a lot of energy from the heat, thereby decomposing into aluminum and oxygen.
- Observable phenomena:
During the reaction process, the Al2O3 compound will transform from a solid state into a gaseous state (aluminum and oxygen). This phenomenon can be observed if carried out under laboratory conditions. However, due to the very high reaction temperature, this experiment cannot be performed at home or in an environment that is not safe enough.
