Gas A+Na_(2)CO_(3)+H_(2)O to B+C(gas) B+Na_(2)CO_(3) to D +C"(gas)"+H_(2)O D+S overset(Delta)to E Which of the following are correct?

Answer»

A is `SO_(2)`
D is `Na_(2)SO_(3)`
C is `CO_(2)`
E is `Na_(2)S_(2)O_(3)`

Solution :`Na_(2)CO_(3)+UNDERSET((A))(2SO_(2))+H_(2)O to underset((B))(2NaHCO_(3))+underset((C ))(CO_(2))`
`NaHSO_(3)+Na_(2)CO_(3) to underset((D))(Na_(2)SO_(3))+underset((C ))(CO_(2))+H_(2)O, underset((D))(Na_(2)SO_(3))+underset("(sulphur)")(S) to underset((E ))(Na_(2)S_(2)O_(3))`
