Question

based on the reaction given below arrange the metals involved in these reactions decreasing order of reactivity and write nature of reactions. a- Zn+CuSo4 -------> ZnSo4+Cu. b-. Cu+2AgNo3----->Cu(No3)2+Ag
c-. Zn+FeSo4-------ZnSo4+Fe
d-. Fe+CuSo4------>FeSo4+Cu​

Answer 1

Answer:

according to the reactivity order.......every metal displace another metal which comes below in reactivity series.

1. zn removes cu ; so cu is placed below from zn.
2. cu removes ag ; so ag placed below cu.
3. zn replace fe so ; fe placed below zn.
4. and fe replace cu ; so cu placed below the fe.

Explanation:

so answer is :- fe > cu> zn> ag.

all the reactions are example of displacement reaction.

Answer 2

Answer: Zn > Fe>Cu >Ag

Explanation: here Zn displaces fe and Cu

So its reactivity is greater

Cu displaces Ag so its reactivity is greater than silver

Fe displaces Cu therefore its reactivity is more than copper
