       column A          column  B
1. `""2H_2 + O_2 → 2H_2O` A. This reaction is not         possible 
2. `""H_2+CI_2 →2HCI` B.This reaction is exothermic to the extent of explosion 
3.`""ZaO+ H^2→Zn +H_2O` C.This reaction is known as Haber process 
4.`""Cu + H_2SO^4 → CuSO_4 + H_2 ` D.This reaction illustrates the reducing property of bydrogen 
5.`""N_2 +3H_2 → 2NH_3 +heat ` E. This reaction takes place in diffused sunlight 
  F. This reaction is a method of preparation of hydrogen
