Question

On heating blue coloured Copper Nitrate
Copper Oxide (Black), Brown gas X is
evolved
i) write the balanced Chemical equation
ii) Name the gas X
iii) Identify the type of reaction.​

Answer 1

Explanation:

1) $2Cu(NO)_3$ → $2CuO$ + $4NO_2$ + $O_2$

2) Nitrogen dioxide is brown fume

3) Decompostion reaction

Answer 2

Answer:

i) $2Cu(NO_{3}).3H_{2}O$ → $2CuO+4NO_{2}+0_{2}+6H_{2}O$

ii) The gas x is $NO_{2}$`.

iii) The reaction is a decomposition reaction.
