Question

answer this correctly plzz​

Answer 1

1- Displacement Reaction is a kind of reaction in which a more reactive element displaces a less reactive element from its compound.

2- This reaction is not possible as Cu is less reactive than Fe

3- This is because iron displaces Cu to form ferrous sulphate, which is green in colour.

4- Precautions are:
-All the beakers/apparatus should be washed with distilled water.

5-It is a chemical change. This is because of formation of a new substance

Answer 2

1. A reaction in which a high reactive element displace the other less reactive element is known as displacement reaction...

Example.. CuSo4 + Fe --》FeSo4+Cu

2. This reaction is not possible because copper is less reactive than iron so it can not displace iron..

3. When iron nail dipped in CuSo4 (blue )solution then displacement reaction takes place in which iron displace copper so solution become green.

4. Precautions :

We should careful about, that the high reactive element should displace the other less reactive..

5.Displacement is chemical reaction because acc. to reactivity series those element are high reactive can replace the lower reactive element..
