Question

what is displacement reaction? which rule governs displacement of an element in a compound by another element? give one example of each

Answer 1

Answer:

Displacement reaction means one element displaces other element from its compound to form another compound .

Eg fe + cucl2 ---> fecl2 + cu

Answer 2

Answer:

when the higher reactive element replaces the lesser reactive element from the solution is known as displacement reaction,

the rule it the higher reactive element replaces the lesser reactive element.

for eg

Zn+cuso4=znso4+cu

as zinc is more reactive than copper so it replaces the element from the reaction.
