Answer:
Double-displacement reaction
Explanation:
In double-displacement reaction, aka. double-replacement reaction, the cation of one compound is swapped with the cation of another. They have the general structure:
AB + CD ---> AD + CB
In this case, the silver cation (Ag⁺) from AgNO₃ is swapped with the hydrogen cation (H⁺) of HCl.
The complete balanced equation is:
HCl + AgNO₃ ---> AgCl + HNO₃
