Some metal oxides that decompose when heated include lead(II) oxide (PbO), Mercury(I) oxide (Hg2O), and copper(II) oxide (CuO). When heated, these metal oxides break down into their respective metal and oxygen gas.

When heated what do metallic chlorates decompose into?

When heated, metallic chlorates decompose into metal chlorides and oxygen gas. This reaction is known as thermal decomposition, where the compound breaks down into simpler substances due to the input of heat energy.


What does not decompose when heated with a Bunsen burner?

Certain metals, such as gold and platinum, do not decompose when heated with a Bunsen burner due to their high melting points and chemical stability. These metals do not react with oxygen in the air at the temperatures typically achieved with a Bunsen burner, allowing them to maintain their integrity without decomposing.
