Final answer:
The reaction in question is not a combustion reaction but a decomposition reaction, where sodium hydroxide decomposes into sodium oxide and water vapor.
Step-by-step explanation:
The reaction 2NaOH(s) → Na₂O(s) + H₂O(g) is not a combustion reaction. Combustion reactions typically involve a fuel, usually a hydrocarbon, reacting with an oxidant to produce carbon dioxide and water in the presence of heat. The reaction given is actually a decomposition reaction, where a compound breaks down into simpler substances. The correct statement is False.
