Question

On heating a blue coloured powder of copper(II) nitrate in
a boiling test tube, copper oxide(black), oxygen gas and a
brown gas 'X' is formed.
(a) Identify gas 'X'
(b) Write the balanced equation for the above reaction.
(c) Identify the type of reaction.
(d) What product 'A' will be formed when gas 'X' is
dissolved in water
(e) What effect will ‘A’ have on litmus paper.
→please don't give any unnecessary answer​

Answer 1

Answer:

a)nitrogen dioxide

b)2Cu(N2O3)2+HEAT→2CuO+2O2+N2

c)Endothermic reaction

d)NH3+NO will formed

e)blue

Answer 2

(a) that brown gas is nitrogen di oxide..

(b) 2Cu(NO3)2(s) ——> 2CuO(s)+ O2(g) + 4NO2(g)

balanced chemical equation..

(c) It is a decomposition reaction as well as endothermic reaction because energy is supplied in the form of heat...

(d) The product 'A' will be Nitric acid (HNO3) on dissolving Nitrogen di oxide (NO2) in water...

(e) Nitric acid ('A') will turn blue litmus paper red..

hope it will help you....
