Question

On heating blue coloured powder of copper 2 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) weite balanced equation of the reaction

Answer 1

Answer:

The type of reaction involved here is decomposition reaction.

The gas X is nitrogen dioxide NO2.

The balanced equation of the reaction is:

2Cu(NO3)2–––}2CuO+O2+4NO2

Explanation:

Decomposition reaction means the separation or the degradation of the constituents of the compound. Here we have the compound as nitrate salt and this always degrades to x oxide, oxygen and nitrogen dioxide. x is the acid radicle.
