Answer:
On Heating Blue Coloured powder of copper II nitrate in a boiling tube black copper oxide o2 and a brown gas X is formed a Identify the type of reaction and the gas x B write balanced chemical equation of the reaction C Write the PH range
When this anhydrous copper (II) nitrate is further heated it gives a black residue of copper oxide and also gives out a brown gas i.e., of nitrogen dioxide and a colorless gas which is of oxygen. Therefore, the gases X and Y are oxygen and nitrogen dioxide respectively.
