when wate ris adde to metallic oxide it forms a hard substance
When water is mixed with a metallic oxide, a metal hydroxide is typically formed. This reaction is known as a neutralization reaction, which involves the combination of the hydroxide ion from water with the metal ion from the metallic oxide.
Aluminum oxide is not considered metallic because it is a ceramic material. It is a compound formed between aluminum and oxygen, and it exhibits properties such as high hardness, electrical insulation, and thermal resistance.
The substance formed when iron is heated in the presence of oxygen is called iron oxide, commonly known as rust.
"Metallic oxide" could refer to many different chemicals. Of course if they are lead oxides, there will be lead in them. Ferrous oxide on the other hand, would not have lead, unless the lead were a contaminant.
Calcium oxide is formed in a blast furnace as a byproduct of the smelting process when limestone, which contains calcium carbonate, is added to the furnace. The intense heat of the furnace decomposes the calcium carbonate into calcium oxide and carbon dioxide. The calcium oxide is then collected as a solid residue.

mageneium oxide
Metallic oxides would not normally decompose as such. Most can be smelted with some form of carbon, in which case carbon monoxide or carbon dioxide is formed.
lead oxide + carbon-> lead + carbon dioxide

When copper is heated, it undergoes oxidation and forms copper oxide as the main product. If the heating is carried out in the presence of oxygen, copper oxide (CuO) is formed. If the oxygen is limited, copper(I) oxide (Cu2O) can also be formed.
The darks substance is copper oxide, formed when the copper reacts with atmospheric oxygen.
potassium oxide
Carbon dioxide is a covalent oxide, specifically a non-metallic oxide. It is formed by the combination of carbon and oxygen atoms, and primarily exists as a gas at room temperature.
