Give a balanced chemical equations for the action of sulphuric acid on each of the following:
(A) Potassium hydrogen carbonate
(B) Sulphur

Explanation

(1) `underset("Potassium hydrogen carbonate")(2KHCO_(3))+ underset("Sulphuric acid(dil.)")(H_(2)SO_(4)) to underset("Potassium sulphate")(K_(2)SO_(4))+ underset("water")(2H_(2)O)+ underset("Carbon dioxide")(2CO_(2)uarr)`
(2) `underset("Sulphur")(S)+underset("Sulphuric acid(dil.)")(H_(2)SO_(4)) to underset("Sulphur dioxide")(3SO_(2)uarr) + underset("water")(2H_(2)O)`
