What Is The Total Ionic Equation For Nitric Acid And Barium Carbonate?

Barium carbonate (s) + nitric acid:

BaCO3(s) + HNO3 (aq) ---> Ba(NO3)2 + + H2CO3 >>> Ba(NO3)2 + H2(l) + CO2 (g)

Balanced equation

BaCO3(s) +  2HNO3 (aq) ---> Ba(NO3)2 + H2(l) + CO2 (g)

Solubility
BaCO3(s) +  HNO3 (aq) ---> Ba(NO3)2 (aq) +  CO2(g) + H2O(l)

Net-ionic equation
BaCO3(s) +  H+ (aq) ---> Ba2+(aq) +  CO2(g) + H2O(l)

Barium carbonate and nitric acid will turn into Barium nitrate , water and carbon dioxide.

HNO3 + BaCO3 = Ba(NO3)2 +H2O +CO2

======
HNO3 + BaCO3 = Ba(NO3)2 + H2CO3
H2CO3 decomposes in H2O and CO2 -- that's what produces the fizz in Coca-Cola, Pepsi etc.
HNO3 + BaCO3 = Ba(NO3)2 + H2O + CO2
(we replace H2CO3 with H2O and CO2)
Balancing, we have left:
2HNO3 + BaCO3 = Ba(NO3)2 + H2O + CO2
Let's check it:
Left: 2 H atoms (HNO3) right: 2 H atoms (H2O)
left: 2 NO3 groups (HNO3) right: 2 NO3 groups (Ba(NO3)2)
left: 1 Ba atom (BaCO3) right: 1 Ba atom (Ba(NO3)2)
left: 3 O atoms (BaCO3) right: 3 O atoms (H2O, CO2)
So the equation is balanced:
2HNO3 + BaCO3 = Ba(NO3)2 + H2O + CO2
