Answer 2

Answer:

displacement reacn includes displacement of one metal or non metal of lower reactivity while that in double displacement ,, they actually interchange their positions//

Explanation:

cuso4 +Zn -----------`,     Znso4 +cu    - displacement reacn

NaCO3 +2HCl -----------,`     NaCl + H2CO3    - double displacement

( as in 1st cu gets displaced by zn ,, while in next they interchange their anions)

/

it takes place in their elecrtrolytes////

still any querry then hit a like and ask?? and mark me brainliest... thanks
