ng produces copper oxide(black), oxygen gas and a brown gas x.() Identify the brown gas X evolved.(i) Write a balanced chemical equation of the reaction.(iii) Identify the type of reaction.Giv) What could be the pH range of the aqueous solution of the gas X? |
|
Answer» (i)The brown gas X is nitrogen dioxide, NO2.(ii) 2Cu(NO3)2(s) --heat-->2CuO(s) + 4NO2(g) + O2(g) (iii) Thermal decomposition.(iv)pH< 7Reason : NO2 dissolves in water to form acidic solution (pH range below 7). thanks |
