Sodium Hydrogen Carbonate

Write the balanced chemical equations for the following reaction. (a) Sodium carbonate on reaction with hydrochloric acid in equal molar concentrations gives sodium chloride and sodium hydrogen carbonate. (b) Sodium hydrogen carbonate on reaction with hydrochloric acid gives sodium chloride, water and liberates carbon dioxide. (c) Copper sulphate on treatment with potassium iodide precipitates cuprous iodide iodide (Cu_(2)I_(2)) , liberates iodine gas and also forms potassium sulphate.
