Question

Gaseous water and solid sodium oxide are formed by the decomposition of solid sodium hydroxide . Write a balanced chemical equation for this reaction.

Answer 1

Sodium hydroxide = NaOH
Sodium oxide = Na2O
Water = H2O

The balanced chemical equation would be written as:

2NaOH = Na2O + H2O

A decomposition reaction involves one substance splitting into smaller molecules. For this case, the smaller molecules would be sodium oxide and water. Hope this answers the question.
