Question

Higher oxides of metal on heating produces its lower oxides​

Answer 1

Answer:

Metal oxides can be decomposed by heat to give the metal and oxygen. This is true of every metal oxide. The more reactive the metal is (the higher in the ECS), the higher the temperature required to do this. ... The temperature of a Bunsen flame allows some metal oxides lower in the ECS to undergo thermal decomposition.

Answer 2

Oxide, any of a large and important class of chemical compounds in which oxygen is combined with another element. With the exception of the lighter inert gases (helium [He], neon [Ne], argon [Ar], and krypton [Kr]), oxygen (O) forms at least one binary oxide with each of the elements.
