Question

The reaction Ba(NO3)2(aq) + Na2SO4(aq) → 2NaNO3(aq) + BaSO4(s) goes to completion because a

Answer 1

Ba(NO₃)₂ + Na₂SO₄ → 2NaNO₃ + BaSO₄

The reaction goes to completion because it has the same amount of elements in the reactants and products.

Answer 2

Answer:

This reaction is completed by a double displacement

A double displacement occurs when two different salts are mixed in an aqueous state, since when they dissolve a salt their ions are dissociated and when mixed with another salt in an aqueous state they combine and form two new compounds

Double displacement reactions

$AB + CD\longrightarrow AC+ BD$

$Ba(NO_3)_2+Na_2SO_4 \longrightarrow 2NaNO_3 +BaSO_4$
