Answer:
The chemical equation 2AgNO3 + Mg(OH)2 → 2AgOH + Mg(NO3)2 represents a double replacement reaction. In this type of reaction, the cations and anions of two different compounds exchange places with each other to form two new compounds. In the given equation, silver nitrate (AgNO3) reacts with magnesium hydroxide (Mg(OH)2) to form silver hydroxide (AgOH) and magnesium nitrate (Mg(NO3)2).
