Predicting Reaction: Ca(NO3)2 + NaHCO3 --> Ca(HCO3)2 or CaCO3 + NaNO3 + H20?

[8point1]

Homework Statement

predict the reaction:

Ca(NO₃)₂ (aq) + NaHCO₃ (aq) ----->

The Attempt at a Solution

Ca(NO₃)₂ (aq) + NaHCO₃ (aq) -----> Ca(HCO₃)₂ (s) + NaNO₃ (aq)

OR


Ca(NO₃)₂ (aq) + NaHCO₃ (aq) -----> CaCO₃ (s) + NaNO₃ (aq) + H20 (l)

Will Ca²⁺ + CO₃^2- combine, and H+ comes off to makeH₂0? I can't decide which is right. How can I tell if H20 will form or not?
