Question

Na=NaCl=HCl=HCl=CaCl2=AgCl

Answer 1

1)2Na + Cl2 = 2NaCl;

2)2NaCl + H2SO4 = Na2SO4 + 2HCl

3)Ca + 2HCl = CaCl2 + H2↑

4)CaCl2+2AgNO3=2AgCl+Ca(NO3)2

Answer 2

I'm sorry, but that statement is not correct. NaCl, HCl, CaCl2, and AgCl are all different compounds with different chemical properties and structures.

NaCl, also known as sodium chloride, is a compound made up of sodium cations (Na+) and chloride anions (Cl-). It is a common salt that is used in many applications, including food seasoning and water softening.

HCl, also known as hydrochloric acid, is a strong acid composed of hydrogen cations (H+) and chloride anions (Cl-). It is used in a variety of industrial processes and is also found naturally in the stomach, where it helps break down food.

CaCl2, also known as calcium chloride, is a salt composed of calcium cations (Ca2+) and chloride anions (Cl-). It is used for de-icing roads, in the production of concrete, and in other industrial applications.

AgCl, also known as silver chloride, is a white, crystalline compound made up of silver cations (Ag+) and chloride anions (Cl-). It is used in photography and in the manufacture of various electronic components.

Although all of these compounds contain chloride anions, they have different cations and different chemical properties. So, Na=NaCl=HCl=HCl=CaCl2=AgCl is not a valid statement.
