Question

2 metallic oxides which decompose on heating​

Answer 1

Answer:

Mercury(II) oxide, a red solid, decomposes when heated to produce mercury and oxygen gas. A reaction is also considered to be a decomposition reaction even when one or more of the products are still compounds. A metal carbonate decomposes into a metal oxide and carbon dioxide gas.

Explanation:

Answer 2

Mercury(II) oxide and Magnesium (II) oxide are the  2 metallic oxides which decompose on heating.​

Explanation:

• Mercury(II) oxide is a kind of metal which is heated it gives the mercury with the liberation of oxygen gas.

• It also considered as the product of decomposition reaction

• A metal carbonate decomposes into a metal oxide and carbon dioxide gas.

• This reaction takes place at a very high temperature.

              $HgO\rightarrow Hg+O_2$

• Magnesium (II) oxide has the formula MgO and it is a metallic oxides. On heating, the MgO gets decomposed into magnesium and oxygen.

• The reaction is as follows:-

            $2MgO \rightarrow 2Mg + O_2$
