    Answer: react each with a dilute strong acid, such as sulfuric acid

    the NaHCO3 will leave a clear solution (sodium) after bubbling

    NaHCO3 + H2SO4 (aq) >>> CO2 (g) + H20 + Na2SO4 (in solution)

    Calclum will leave a NOT clear liquid (Calcium)

    Ca (HCO3) 2 + H2SO4 (aq) >>> CO2 (g) + H20 + CaSO4 (precipate)
