Book Free DemoWrite a long answer to the following questions:
On heating blue coloured powder of copper (II) nitrate in a boiling tube, copper oxide (black), oxygen gas and a brown gas X is formed.
(a) Write a balanced chemical equation of the reaction.
(b) Identity the brown gas X evolved.
(c) Identity the type of reaction.
(d) What could be the pH range of aqueous solution of the gas X?
(a) Write a balanced chemical equation of the reaction.
(b) Identity the brown gas X evolved.
(c) Identity the type of reaction.
(d) What could be the pH range of aqueous solution of the gas X?
i. The balanced chemical equation for the reaction:
\(2Cu(NO_3)_2\)(s) \(\xrightarrow[]{Heat}\)
ii. The brown gas \(X\) that evolved in the reaction is .
iii. The reaction mentioned above type is a reaction.
iv. The pH range of the aqueous solution of the gas \(X\) is below because oxides of non-metals are generally in nature.
