Question

Complete and balance the molecular equation for the reaction of aqueous sodium sulfate, Na2SO4, and aqueous barium nitrate, Ba(NO3)2.
What is the molecular equation?
what is the net ionic equation?

Answer 1

Molecular equation: $Na_2SO_4(aq)+Ba(NO_3)_2(aq)\to BaSO_4(s)+2NaNO_3(aq)$

Net ionic equation:

$2Na^++SO_4^{-2}+Ba^{+2}+2NO_3^-\to BaSO_4(s)+2Na^++2NO_3^-$
