question 17 (3 points)

double displacement reaction

(Acid- base)

Explanation:

Double Displacement Reaction : The reaction in which the anion and cations of two different salts exchange their position to form new products.

Here ,

Mg2+ is exhanged by H+   to form H2O

SO4 2- by OH-                     to form H2O

H+ is exhanged by Mg+      to form MgSO4

OH- by SO4 (2-)                   to form MgSO4

let that person have a turn to speak : )
