Question

on heating blue colored powder of copper nitrate in a boiling tube, copper oxide ,oxygen gas and a brown colored gas X is formed.
[A] Write a balanced chemical equation for the reaction.
{B} identify the brown gas X .
[C] identify the type of reaction.

Answer 1

Answer:

• 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.
