Respuesta :
Answer: [tex]Ca(NO_3)_2[/tex]
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which on e of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation for a precipitation reaction is:
[tex]2Na_3PO_4(aq)+3Ca(NO_3)_2(aq)\rightarrow Ca_3(PO_4)_2(s)+6NaNO_3(aq)[/tex]
The salt that should be participated in the double displacement reaction should form the insoluble compound(s) i.e. Ca(NO3)2.
What is a double displacement reaction?
It is the one where the ions should be exchanged. The salts should be soluble in water that should be designated by symbol and can be insoluble in water also same in the solid form. The same should be presented by (s) when the chemical formulas are mentioned. Also, it is one of the product that should be created known as the precipitation reaction.
