Problem

Give the net ionic equation for the reaction (if any) that occurs when aqueous solutions of Na2COand HCl are mixed.

a) 2 H+(aq) + CO32-(aq) → H2CO3(s)
b) 2 Na+(aq) + CO32-(aq) + 2 H+(aq) + 2 Cl -(aq) → H2CO3(s) + 2 NaCl(aq)
c) 2 H+(aq) + CO32-(aq) →  H2O(l) + CO2(g)
d) 2 Na+(aq) + CO32-(aq) + 2 H+(aq) + 2 Cl -(aq) → H2CO3(s) + 2 Na+(aq) + 2 Cl -(aq) 
e) No reaction occurs.
