Detailed explanation-1: -Lead acetate can be used in place of lead nitrate because like lead nitrate, it is also water soluble. It will dissociate into Pb2+ ions in water and produce lead iodide.
Detailed explanation-2: -Examples of double-displacement reactions include: Sodium hydroxide (a base) reacts with ammonium chloride (salt) to form sodium chloride, hydrochloric acid, and water. Silver nitrate reacts with sodium chloride to form silver chloride and sodium nitrate.
Detailed explanation-3: -If you combine vinegar and baking soda for a chemical volcano or milk with baking powder in a recipe, you experience a double displacement, or metathesis reaction (plus some others.) The ingredients recombine to produce carbon dioxide gas and water.
Detailed explanation-4: -The double-replacement reaction generally takes the form of AB + CD → AD + CB where A and C are positively-charged cations, while B and D are negatively-charged anions.
