Homework Help: Predicing Reaction help

  1. Feb 10, 2012 #1
    1. The problem statement, all variables and given/known data

    predict the reaction:

    Ca(NO3)2 (aq) + NaHCO3 (aq) ----->

    3. The attempt at a solution

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


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

    Will Ca2+ + CO32- combine, and H+ comes off to makeH20? I can't decide which is right. How can I tell if H20 will form or not?
