Answer : Barium sulfate[tex](BaSO_4)[/tex] and Sodium nitrate[tex](NaNO_3)[/tex] are produced during replacement reaction.
Explanation :
Double-displacement reaction : It is a type of chemical reaction in which two reactants exchange ions to form two new compounds.
The Net balanced chemical reaction is ,
[tex]Ba(NO_3)_2(aq)+Na_2SO_4(aq)\rightarrow BaSO_4(aq)+2NaNO_3(aq)[/tex]
This is a double-displacement reaction.
In this reaction, barium nitrate react with the sodium sulfate to produce barium sulfate and sodium nitrate.
