Question

Identify the element which is most reactive and the element which is least reactive? A 2 O 3 +2B B2O 3 +2A; 3CSO 4 +2B B 2 (SO 4 ) 3 +3C; 3CO+2A A 2 O+3C​

Answer 1

Answer:

In the reaction (iii) 3 CO + 2 A → A2O3 + 3 C the element A replaces the element C from its salt solution. Hence, the element A is more reactive than the element C. Thus, among the elements A, B and C, the least reactive element is the element C and most reactive element is B.
