The chemical equation is 2NaOH -> 2Na + H2 + O2.

Detailed information about the 2NaOH -> 2Na + H₂ + O₂equation -> : This equation describes the decomposition process of sodium hydroxide (NaOH), which decomposes into sodium (Na), hydrogen (H₂), and oxygen (O₂).

Reaction conditions:
For the reaction to occur, the temperature needs to be extremely high, usually around 300 to 400 degrees Celsius.

Reaction process:
When the temperature increases to the necessary level, the NaOH molecules begin to decompose. The Na+ ions separate and combine with electrons to form sodium atoms. The OH- ions separate and combine with protons to form hydrogen and oxygen molecules.

Phenomena that occur:
Initially, the solid NaOH can be seen melting due to the increased temperature. Then, there may be white smoke (water vapor formed from the reaction of hydrogen with air) and a bright light due to the reaction of sodium with air. In addition, there may be an unpleasant smell due to the generation of oxygen gas.
