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)
