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.

Does metal oxide decompose when heated?

Metal oxides typically do not decompose when heated, but instead may undergo various chemical reactions such as reduction or oxidation. The specific behavior of a metal oxide when heated will depend on the type of metal and the conditions of heating.

What do metal hydroxides decompose yield?

Metal hydroxides typically decompose to yield metal oxides and water through a process known as thermal decomposition. For example, when copper(II) hydroxide decomposes, it forms copper(II) oxide and water.

Do all carbonates decompose?

Not all carbonates decompose when heated; their behavior depends on the specific type of carbonate. For example, some carbonates, like sodium carbonate, are stable and do not decompose upon heating. However, many metal carbonates, such as calcium carbonate and magnesium carbonate, do decompose at elevated temperatures, releasing carbon dioxide gas and leaving behind metal oxides. The decomposition temperature and products can vary widely among different carbonates.

Can metal oxide sublime?

Metal oxides generally do not sublime under normal conditions; they typically decompose or melt when heated rather than transitioning directly from solid to gas. Sublimation is more characteristic of certain molecular compounds and specific elements, particularly those with weaker intermolecular forces. However, some metal oxides can exhibit vaporization at very high temperatures, but this is not the same as sublimation. In summary, while some metal oxides may release gaseous products upon heating, they do not sublime in the traditional sense.


What metal does not decompose when heated with a Bunsen burner?

Tungsten is a metal that does not decompose when heated with a Bunsen burner due to its high melting point of 3422°C. This property makes tungsten ideal for use in the filament of incandescent light bulbs.

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.
