1. 2Na+2C2H5OH
--->C2H5ONa+H2
In this reaction a displacement reaction is taking place where sodium ethanoate and hydrogen gas produced.
2. CaCO3+ H2O+heat
---> H2O+CO2+CaO
In this reaction calcium carbonate decomposes to form Calcium oxide, carbon dioxide and water
3. No reaction will take place because Barium is less reactive than sodium and barium sulfate cannot displace sodium chloride
