Question

Give a balanced equation for thermal decomposition of.
1-calcium hydroxide

Answer 1

                                  Heat

Calcium Hydroxide  ----------> Calcium oxide + Water

                  Heat

Ca(OH)2  -----------> CaO + H2O

Hope this helps! :)

Answer 2

Answer:

Ca(OH)2 → Ca2+ + 2 OH. When heated to 512 °C, the partial pressure of water in equilibrium with calcium hydroxide reaches 101 kPa (normal atmospheric pressure), which decomposes calcium hydroxide into calcium oxide and water.
