Question

give an example of a double displacement reaction other than the one give answer​

Answer 1

Explanation:

Give an example of a double displacement reaction other than the one given in activity 1.10.

Answer

Pb(NO3)2 (aq) + 2KI (aq) → PbI2 (s) + 2KNO3 (aq)

Lead Nitrate Potassium Iodide Lead Iodide Potassium Nitrate

When the aqueous solution of lead Nitrate is mixed with potassium Iodide, we obtain a precipitate of lead iodide and a solution of potassium nitrate. In double ddisplacement reaction their is exchange of ions between the reactant. In this reaction, the cation Pb2+ and K+ exchange their anions NO3- and I- to give new substance PbI2 and KNO3.

Answer 2

Answer:

HCl + NaOH ------> NaCl + H20(water).
