Question

(a) Write one example for each of decomposion reaction carried out with help of

(i) Electricity (ii) Heat (iii) Light



(b) Which of the following statements is correct and why

copper can displace iron from iron sulphate and iron can displace copper from copper

sulphate solution.​

Answer 1

Answer:

its not decomposion its decomposition reaction,

Ans (a)-(i) electricity:-electrolytic decomposition

(ii)heat :-

(iii)light:-photo decomposition

Ans (b) Iron metal is more reactive than copper. Therefore, iron can displace copper from copper sulphate (CuSO4) solution. Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4)
