Write a balance equation for the reaction of nitric acid (HNO3) with each base solution : [1]. NaHCO3, [2]. MgCO3. ( Please include the phases of the substance)

Answer 1

HNO3(aq) + NaHCO3(s) ==> H2O(l) + CO2(g) + NaNO3(aq)
2HNO3 + MgCO3 ==> Mg(NO3)2 + H2O + CO2
I've left the phases for you on #2.
