Answer» Question 3(iii) Samples of four metals A, B, C and D were taken and added to the following solution one by one. The results obtained have been tabulated as follows: $\begin{matrix} M e t a l & I r o n (I I) s u l p h a t e & C o o p e r (I I) s u l p h a t e & Z i n c s u l p h a t e & S i l v e r n i t r a t e A . & N o r e a c t i o n & D i s p l a c e m e n t B . & D i s p l a c e m e n t & N o r e a c t i o n C . & N o r e a c t i o n & N o r e a c t i o n & N o r e a c t i o n & D i s p l a c e m e n t D . & N o r e a c t i o n & N o r e a c t i o n & N o r e a c t i o n & N o r e a c t i o n \end{matrix}$ Use the Table above to answer the following questions about metals A, B, C and D. (iii) Arrange the metals A, B, C and D in the decreasing order of reactivity.
