Solid potassium oxide and gaseous water are produced by the decomposition of solid potassium hydroxide . Write a balanced chemical equation for this reaction.

2 KOH → H₂O + K₂O

Explanation:

When KOH descomposes in potassium oxide, K₂O and water, H₂O.

The unbalanced equation is:

KOH → H₂O + K₂O

As you can see, 2 hydrogen, potassium and oxygen atoms are produced, to balance this equation we can write:

2 KOH → H₂O + K₂O

This is the balanced equation because 2 atoms of K, H and O are in reactants and products
