When Beryllium nitrate, , is heated, the thermal decomposition reaction stops prematurely after a sh — s Block Elements Chemistry Question

💡 Solution & Explanation

When $Be(NO_3)_2$ is heated, it decomposes to form beryllium oxide ($BeO$), nitrogen dioxide, and oxygen. However, the $BeO$ forms a tough, inert protective film on the surface of the unreacted nitrate, which prevents further decomposition.
