The scheme of transformations is given: CaO → X ⎯Na2 CO3 → CaCO3 → CO2 Write down the molecular equations of the reactions, which can be used to carry out the indicated transformations. For the second transformation, write the abbreviated ionic reaction equation
CaO → X → Na2CO3 → CaCO3 → CO2
CO2 + CaO → CaCO3
CaCO3 + Na2S → Na2CO3 + CaS
Ca (+1) + S (-2) → CaS
CaCl2 + Na2CO3 → NaCl + CaCO3
CaCO3 → CO2 + CaO
