Answer 1

$\huge{\underline{\mathtt{\blue{A}\red{N}\pink{S}\green{W}\purple{E}\orange{R}}}}$

Explanation:

It is a type of reaction in which exchange of two ions takes place.

Eg. BaCl2+Na2SO4-------BaSO4+2NaCl

Answer 2

Answer:

HCl + NaF = NaCl + HF

Explanation:

A double displacement reaction is where an element replaces another element in a different compound. This occurs due to the difference in reactivities of these elements with the respective counter elements.

In this case F⁻ replaces Cl⁻ in HCl because fluorine is more reactive towards hydrogen, and form HF and NaCl.
