Identify the double displacement reactions among the following: 1. KCl(aq) + AgNO3(aq) - AgCl(s) + KNO3(aq) 2. Na2SO4(aq) + BaCl2(aq) →BaSO4(s) + 2NaCl(aq) 3. H2SO4((aq) + 2NaOH(aq) Na2SO4((aq) + 2H2O(1) A) 1 and 3 only B) 2 and 3 only C) 1 and 2 only D) All of 1, 2, and 3 E) None of 1, 2, and 3

Respuesta :

Answer: D

Explanation: in double decomposition the products formed are precipitate and the reaction is ionic in nature.

Answer:

[tex]1.KCl(aq) + AgNO3(aq) - AgCl(s) + KNO3(aq)[/tex]

[tex]2.Na2SO4(aq) + BaCl2(aq) - BaSO4(s) + 2NaCl(aq)[/tex]

[tex]3.H2SO4((aq) + 2NaOH(aq) Na2SO4((aq) + 2H2O(1)[/tex]

Correct Option is (D) All of 1, 2 and 3

Explanation:

Double displacement reactions:

  • This reactions usually take place in aqueous solutions in which the ions accelerate and there is a replacement of ions.
  • Meanwhile, the reactions are ionic in nature.
  • A double displacement reaction is a reaction where the positive and negative ions of pair ionic compounds shift places to form two further compounds.
  • General form of Double displacement reaction:
