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 sodim chloride, water and liberates carbon dioxide. (c) Copper sulphate on tretment with potassium iodide precipitates cuprous iodide iodide `(Cu_(2)I_(2))`, liberates iodine gas and also forms potassium sulphate.
